Year Inside, Hour Outside

Go To
Her absence lasted as long as it took you to read this.

"Inside, time moves at 365.24 times that of this dimension. In Goku terms: one day out here, one year in there."
Mr. Popo, Dragon Ball Z Abridged


If you're Trapped in Another World, the major disruption in your life is going to be everyone noticing you're gone. How can you keep the Masquerade going if you're ducking out for hours on end without your parents or boss wondering where you went?

Luckily, the dimension has rules of its own. One convenience is time in a Magical Land keeps moving while in Real Life, Time Stands Still (or very close to it). You can go from Crash-Into Hello to defeating the Big Bad all in one weekend. So long as you don't get into the relative past and future, this is a way of playing with time without needing to bother with all the headache-inducing tropes of Time Travel.

If the change in time flow is constant, then the hero may save the day in the other world and jump back to their home dimension for a short while, then return... only to find centuries have passed. On the other hand, sometimes the time flow is a lot more convenient, the "same" amount of time seems to pass when they're in their own world.


Time isn't always on your side, however. The plot might not deign to give you the MacGuffin necessary to get out, for instance. And if where you're going is rather unpleasant, or even if there's not much to do when you get there, this scenario could very well end in tears.

Be careful that this doesn't go in reverse, though. If more time passed in the "real" world, you're looking at Year Outside, Hour Inside. If you slept while more time than you thought passed in the "real" world, you're looking at the Rip Van Winkle. If the relative flow of time varies, it's Narnia Time. In hard science fiction, Time Dilation will generally be used instead, as it's a real principle of physics. In other words, Time Is Dangerous. (Examples of Time Dilation should go on that page, not this one.) In softer works, expect to see a time dilation field or other Technobabble explanations instead.

    Anime and Manga 
  • The entire plot of Accel World. The main characters duel in a full-dive virtual world where time is sped up by a factor of 1000. If you lose, you lose Points, if you win you gain them, and if you lose all of them the game deinstalls and you lose every memory related to it. It takes ten Points to enter the Unlimited Field, where you can fight NPCs and basically stay as long as you want (since 45 minutes in real life equals about a month in-game). The time the veterans have spent there is unknown, but it's unlikely to be less than a couple of decades.
  • Angélique:
    • Played with in the manga version of the original Angélique where in one chapter, the heroine has to select a priest to deliver her message to the people of the continent she is cultivating. Due to the difference in the flow of time between the Sanctuary and said continent, she meets her choice as a child one day and then as an adult the next, causing her a great deal of confusion.
    • The actual amount of time that passes in the Holy Land/Sanctuary vs the rest of the universe is incredibly wonky and often contradicts itself if it means letting a main character live. For example, in Koi suru Tenshi Angelique, it's mentioned that one year in the Shinchou universe's Sanctuary equals several decades outside. If that's the case, than a lot of the Seijuu universe's guardians would have probably died of old age before Ange got to them (and they probably wouldn't have shown up in multiple games after their debuts that probably take place months apart time wise.)
  • In New World Online the VRMMORPG of BOFURI: I Don't Want to Get Hurt, so I'll Max Out My Defense, one week within the virtual world is two hours in the real world.
  • Bleach:
    • The pathway from the Human world to Soul Society acts like this. You usually couldn't stay there for too long before an Eldritch Abomination comes and sucks you into another time (or just wipes you from existence) but after it was gone Isshin is able to extend the time difference even longer so that an hour outside would turn into 2000 hours inside.
    • Also, Yukio's Fullbring, Invaders Must Die, has a fast forward mode that allows an indeterminate amount of training to take place in a few hours. However much it is, it's enough to let Ichigo finish his Fullbring training.
  • In Crimson Spell, Halvir spends three months in a Lotus-Eater Machine before he even bothers to get around investigating what exactly is going on - and then a little longer to indulge in a Twin Threesome Fantasy once he's figured it out - after which the events of the main storyline resume with no apparent interruption.
  • Digimon:
    • In Digimon Adventure, the Digital World works on a one day = one minute ratio. However, when it is reformatted at the end of the season, it and the real world begin working in the same time frame, allowing the Digimon Adventure 02 kids to treat saving both worlds as an after-school activity.
    • Digimon Frontier also features a time discrepancy: comparing the first and last episodes indicates that no more than ten minutes elapsed in the real world compared to months in the Digital World. However, in one episode Takuya somehow goes back in time to before he went to the Digital World, implying that the relationship between Real World time and Digital World time is more complicated than it appears.
    • In Digimon Fusion, virtually no time had passed from the point our three heroes entered the Digital World to their return to the Real World mid-season.
  • One Doraemon movie had Doraemon's magical doorway lead into another world; relativistic effects made it so that one day in the other world was nothing more than an hour on Earth.
  • Dragon Ball:
    • The Hyperbolic Time Chamber, known as the Room of Spirit and Time in Japanese, is introduced during the Android arc. It's an alternate dimension accessed from Kami's Lookout, and one day outside equals one year inside. It allows our heroes to get some much-needed training they otherwise wouldn't have time for. Later on, during the Buu arc, Piccolo exploits this trope by having Trunks and Goten practice the Fusion Dance in the Time Chamber while he stalls Buu outside; even if he can't keep Buu busy for more than a few minutes, that still gives Goten and Trunks hours of practice time.
    • The Room reappears in Dragon Ball Super when, in preparation for an inter-universal combat tournament, Goku and Vegeta spend three years/days inside training.
  • In Fullmetal Alchemist, time inside the Gate of Truth appears to take no time at all outside; at least when Alphonse sacrifices himself to restore Edward's arm, he has a short conversation with his body first, while Edward's battle with Father seems to have stood still.
    • The exact nature of the Gate is mysterious. It almost seems to be a Place Beyond Time, except that Alphonse's body ages while it's in there. At the same rate as it would have aged in the real world, despite time not usually seeming to pass in the Gate relative to the outside. Alphonse's body seemed to be linked to the physical plane via Edward, so perhaps that connection made it age normally. It also explains why the body didn't starve to death, as Edward eats and sleeps a lot and the characters theorize some of that was transferred to Alphonse's body.
  • Fushigi Yuugi:
    • An interesting variant because all of the events of the Universe of the Four Gods take place in a book. Anything that occurs in the book only takes about as much time in the real world as it would take for someone to read about it.
    • The second part of Fushigi Yuugi, focusing on Miaka and Taka searching for the stones containing his memories as Tamahome, plays with it by having Suzaku-Seikun inhabit Miaka's watch and send them into the original scroll of the Universe. With him in her watch, he only lets them stay in the scroll for as long as it takes for one hour to pass in the real world. This bites them in the back when he transfers into her pager and has no reminder anymore when an hour has passed. Miaka ends up in the scroll for two days, but was gone for three months in the real world.
  • In Futari wa Pretty Cure, Mepple leaves the Garden of Light one day after Mipple does. This translates into about a century in the Garden of Rainbows (i.e. on Earth). When Nagisa and Honoka go to the Garden of Light themselves, the effect ends up being reversed (about a day in the Garden of Light becomes no time at all in the Garden of Rainbows) due to Porun's assistance. In one of the movies, the Garden of Hope seems to work this way on its own, with the entire movie (appearing to take quite a bit of time, possibly even multiple days) happening within just a few minutes.
  • The Hero is Overpowered but Overly Cautious: The unified spirit world, the realm of the gods, is a place where time moves a hundred times slower than in the mortal realms. Seiya takes advantage of this by training in the gods' realm to level up faster than if he trained in a mortal world.
  • Jewelpet Twinkle establishes that time in Jewel Land goes by much faster than in the human world, which is why Akari can go there every day and not worry about skipping school back home. However, to explain why Alma, Yuuma's sister, is the same age as him even though they're living in different worlds, they add that one year in Jewel Land is still one year in the human world, edging this into Narnia Time.
  • In Log Horizon, Shiroe comes to realize this trope is in effect within the world of Elder Tales. When Elder Tales was a game, one in-game day was two real world hours. Doing the math, Shiroe realizes that major dates in the world's history, such as the appearance of adventurers, coincide with real world events, such as the start of the game's open beta testing.
  • In Magic Knight Rayearth, no time at all seems to pass while the title characters are in Cephiro. In fact, one episode of the anime's first season has them seemingly go back to Earth — and time is standing still.
  • The Training Gate arm in MÄR drops people into an Pocket Dimension where the time flow is 60 times the outside time. On their first time inside, Ginta and Jack spend a whopping six months in the Training Gate, while only three days pass outside. Repeated use of the Training Gate allows the heroes enough time to match the abilities of the much more experienced villains. MÄR itself averts the trope; time flows in sync with Earth but the day/night cycles are out of phase. This is shown in the interaction between Koyuki and Princess Snow: when one of them sleeps, she dreams about what the other is doing as she's awake.
  • Mazinger Z: Inverted in a spin-off. Kouji was accidentally thrown in another dimension. He spends roughly one day in that place before returning to his own world. His friends told him he had been missing for one entire month.
  • Mob Psycho 100: Mob sends his soul inside a girl that is possessed by the spirit of Keiji Mogami, then Mob gets tricked and gets placed in an illusionary world by Keiji with his memories altered. While the whole thing seemed like a whole six months for Mob, Reigen and Dimple claim that Mob was gone for about 30 minutes.
  • In Modern Magic Made Simple, Koyomi travels to the past (sort of) by hooking herself up to a viewer, and spends several hours meeting a young Yumiko, obtaining the password she needed to get, and helping to defeat a revived evil mage. Back in the present, she was looking through the viewer for 23 seconds.
  • Monster Rancher: Genki was inside the Monster Rancher world for about a year, but only three hours had passed in his world.
  • In Naruto, Itachi's Tsukuyomi has the ability to do this from a perception standpoint, causing its target to experience days' worth of illusions in mere seconds. Not only that, but he can further stretch time within the illusion so that one second feels like hours.
  • Negima! Magister Negi Magi:
    • Eva's villa in the manga operates on 24-1 ratio. This allows Negi to get a full day's worth of Training from Hell without cutting into his duties as a teacher.
    • Another manga chapter has Negi cramming a month of training into about 3 days using a device similar to Eva's resort. Then he uses a magic scroll with a 72-1 time ratio to squeeze another month of training into one morning.
    • A teacher at Mahora mentions off-handedly that with the links between the magical and mundane worlds severed, the magic world will be advancing faster—about six times. This will let Ala Alba return to school before summer break is over, despite spending months away.
  • In New UFO Baby, Miu spends several months traveling across space. When she returns to Earth, she realizes that only a few hours had passed, and her parents thought that she's just got back from school, as usual.
  • In Nyaruko: Crawling with Love!, Luhy Distone has a door in her apartment that connects to the Room of Spirit and-*achoo!*. In the short story and OVA episode "How to Defeat a Kind Enemy", she spends one month (two hours real-world time) training Nyarko to become a Magical Girl, mostly by channeling the spirit of R. Lee Ermey in Full Metal Jacket.
  • In Only Sense Online, the "Forest Camping Game" event of the titular MMORPG takes place in a special Cyberspace server in which the flow of time has been stretched by about 80 times. This enables the event to last for a week while only taking up 2 hours of real time.
  • In PandoraHearts, people who've been banished to the Abyss and somehow manage to return often find themselves stranded in a different time.
  • In Persona 4: The Animation, Yu gets trapped in an illusion by Shadow Mitsuo where he experiences the team drifting apart as months pass by. Though, after Yosuke pulls him out of it, only several minutes passed after he got trapped.
  • In RahXephon, time inside Tokyo Jupiter passes about six times more slowly than in the outside world. Ayato and Itsuki are twins, but one of them is much older due to living outside of Tokyo.
  • According to the Robotech novelization by Jack Mckinney, this is what gives the Super Dimension Fortress its name: 15 minutes outside is six hours inside.
  • Space Battleship Yamato 2202 introduces the Time Fault, a location on Earth where the timestream is way off-kilter. This was an unforeseen effect of activating the Cosmo Reverse. For every year that passes outside of the Time Fault, ten years passes in the Fault. This becomes a major plot device, as the Terrans quickly take advantage of the area to churn out a fleet of Wave-Motion capable warships in record time. Indeed, the Terran council actually rents some of the place out to their Gamilan allies, so that they could also make new ships.
  • Purgatory in The Seven Deadly Sins runs Year Inside, Minute Outside. Ban goes into Purgatory to look for Meliodas and has apparently been there a long time; the only thing keeping him going being his Immortality. They encounter a creature whose brother was sent to the real world 8 million years ago Purgatory-time.spoiler 
  • Sonic X: Zig-zagged: the one extra day Sonic spends with Chris before going back to his world is treated like a long time by the others back in his world, but the third season shows that the 6 years that had passed in the Distant Finale were only 6 months in Sonic's world. For extra fun, actually managing to teleport to Sonic's world also causes Chris to revert back into the child he was 6 years ago.
  • In Soul Hunter, the Big Bad has a Paopei named Sangashasshokuzu, which uses a series of small black snakes to trap people in a dark and empty dimension where one hour inside equals to a minute outside. Fortunately, all the heroes trapped inside have ways to pass the time avoiding Sanity Slippage... except for one, who, to add insult to injury, is the last to be fred (and by the time he's out he's devolved into The Berserker).
  • Sword Art Online
    • In the virtual reality program known as the Underworld, the setting for the Alicization arc, time flows at a much faster rate compared to the outside world, resulting in centuries passing inside in the space of weeks in the real world. The rate at which the time is accelerated varies- for example, the acceleration is stopped when Kirito contacts Kikuoka from inside the Underworld.
    • Averted in Progressive'. Kirito wonders if something like that is in play in SAO, and briefly hopes that it means that he and the other players haven't been trapped inside for very long, but realizes that this isn't the case.
  • In episode 132 of Tamagotchi, it's implied that time works differently in the ancient Tamagotchi Village compared to the rest of Tamagotchi Planet. Lovelitchi and some of the female Tama-Friends stay in Tamagotchi Village until sunset, but when they come back, it's still earlier in the day and they find Mametchi, Memetchi, and Kuchipatchi getting ready to head off to school.
  • In Tsubasa -RESERVoir CHRoNiCLE- it is mentioned that the time in the place where Fai and Yuui are imprisoned moves differently than on the outside. Presumably slower on the inside, since the entire kingdom of Valeria manages to fall into ruin at their uncle's hands during what seems to be only five or six years for them.
  • In Yu-Gi-Oh!: Capsule Monsters, Yugi and his friends spent several days in the Capsule Monsters world, but only an hour passed in real life.

    Asian Animation 
  • In Nana Moon, Keke inadvertently discovers a section of the moon called the Moon Haven and meets one of its moon genies, Princess Amy. When Keke is asked to stay in Moon Haven and worries that her parents will notice she's gone, Amy mentions that one year in Moon Haven is equivalent to one minute on Earth.

    Card Games 
  • Magic: The Gathering:
    • After an accident involving a time machine on the island of Tolaria, there were pockets of differently moving time. Teferi fell into a slow-moving pocket of energy immediately after catching fire, causing him to burn for 40 years of real time. Meanwhile, a Phyrexian operative fell into a fast-moving pocket of energy, which allowed it centuries to build a Phyrexian army in just a few years of real time.
    • The Scheherezade and Stasis cards have this effect.

    Comic Books 
  • The Marvel Comics storyline The Adventures of Cyclops and Phoenix. Time Travel Hand Waving brings their minds to the far, far future so they can raise the young Cable as the mysterious pair "Redd and Slym". About ten years pass there, with only a few moments passing here. Which is good, because "here", they had fallen face first into water.
  • Stephen Strange once spent five thousand years fighting in the War of the Seven Spheres alongside the Vishanti. When he returned to Earth, only a few months had passed.
  • Justice League of America:
    • In Grant Morrison's "Crisis Times Five!" storyline, The Spectre is tied down and trapped with a civilization on top of him. Zauriel and Green Lantern could free the Spectre... and kill all the innocent people. They jumpstart time so 'the world' comes to an end in about an hour. The aliens don't really figure it out, apart from noticing the Lantern and Zauriel-shaped statues in their lives.
    • The Tower of Babel storyline, where The Flash was struck by a super-speed bullet that played havoc with his powers. By the time he was freed from the effects (a few minute), for him it had felt like -months-. Wonder Woman was also affected similarly, being made to believe she was fighting a perfectly matched opponent while her body gave out (the amount of time it would take for Diana to die of exhaustion would be far more than the few minutes she was disabled in the real world).
  • In the DC comic Lucifer, the titular character creates his own universe in which time runs much, much faster. This becomes an important factor in several stories. A third universe is created in a later storyline that also has an accelerated timestream.
  • Hell also seems to work in much the same way in DC comics books — in the Swamp Thing annual "Down Amongst the Dead Men", Swampy comes across a foe who had died in the previous issue, his body continually being filled with spider eggs that burst open and eat his flesh. The enemy asks how many years he's been enduring this agony and is horrified to find out that he's only been there for one day. A later Secret Six issue confirmed that time is actually slower here, as opposed to just feeling long. This trope occurring doesn't seem to make much sense (if you're there for all eternity, what does it matter how slow the time passes?) until Fridge Brilliance sets in... it's a comic book universe, so it might not be for all eternity.
  • X-Men:
    • Illyana Rasputin, seven-year-old sister of the X-Man Colossus, was lured into the realm of a demonic sorcerer. The X-Men went in and rescued her before any harm was done, but the youngest of them lost her grip for a few seconds as they escaped... and pulled out a fourteen year old teenager with a host of Dark Secrets. There is no set ratio for time in Limbo; in fact, time isn't even linear there.
    • Also in the X-Men-related Marvel Universe was a pocket dimension called The Hill. Colossus' insane brother Mikhail brought a large group of homeless mutants to that place and forced them to fight each other in a Darwinian survival scenario. How fast time passed there compared to the regular universe was never explained. Some characters barely aged in a 10/1 year ratio while others were the grandchildren of those transported there by Mikhail.
    • Eva Bell aka Tempus, one of the mutants that appeared after Avengers vs. X-Men, is a Time Master who can create temporal spheres with these properties. The effect is so powerful that it seems like Time Stands Still. Doctor Strange is impressed (and that's saying something) by her power, claiming that it would take a person within the spheres a hundred years to take a single step.
  • This was supposed to be how Lion-O would train in a pocket dimension in the Darker and Grittier ThunderCats (1985) comic, spending seven years there while a day passed outside. Unfortunately, Mumm-Ra got to him first, and Lion-O emerged a day later to find seven years had passed outside.
  • In Marvel Comics, we have the Macroverse, which combines this and Rip Van Winkle — after Spider-Man and the Fantastic Four visit, one generation has already passed there. When they return, they spend only a few hours, but on Earth, it was two months.
  • Superman:
    • In Superman vs. Muhammad Ali - see part of it here - Superman applied some phlebotinium called a Kryptonian Continuum Disruptor to create a boxing ring where an hour inside was about a minute outside, giving them two months instead of twenty-four hours to teach Superman how to box. Unfortunately, the aliens making them do this — no, not like that — clue in on it and interrupt them after only about two weeks.
    • There was a Superman comic where Supes and Wonder Woman are whisked away by the Norse gods to fight as champions in Ragnarok for a thousand years... while maybe a few days pass in reality. The thing is, Superman and Wonder Woman don't know this... and while Superman starts forgetting the small things about Lois and believes she may well be long dead, he still can't strike anything up with Wonder Woman because he's still devoted to Lois.
    • In Superman: Godfall, Supes becomes trapped in the bottle city of Kandor, and finds that hundreds of years have passed since the last time he visited. The citizens, including Lyla, the Kandorian woman he marries in the storyline, don't realize he is "The Superman of Legend". After all, it has been several generations, and even Supe's original messages of altruism, truth, and justice have been perverted by the citizens into stories of Superman subjugating the Earth as God.
    • In the 3-part (issues #57-59) Superman/Batman story called "Nanopolis", Superman is shrunk down to microscopic levels and helps the tiny civilization he finds there. Batman eventually joins him in an effort to rescue him, and Superman discovers that only a few hours have gone by in the real world while it's been months for him.
  • A certain alien race of recurring Harmless Villains in Invincible comes from an Another Dimension in which time passes much faster than on the Earth where most of the action takes place. When they come to Earth, they age decades in minutes if certain protective devices are disabled. Later, Robot and Monster Girl are accidentally transported to this dimension, but make their way back a few months later. Well, it was months from our perspective — while the rest of the cast assumes it was "just" a few years to them, they were actually gone for thousands of years. They agreed to lie about the amount of time because they think their friends would be weirded out by the truth.
  • In a DC Comics Presents story, a villain, who just attacked Green Lantern Hal Jordan in another dimension, then abducts Superman just as he about save a man falling from a building. After defeating the villain, Superman is brooding that the man must surely be dead now. However, as Jordan guides Superman back, he says not to give up hope as dimensions often have different rates of time progression. In this case, the dimension they are leaving has a much slower rate and arrive back home just in time to save the falling man.
  • In Necrophim, a year in Hell is the same as a millennium in Purgatory.
  • The Disney Ducks Comic Universe "Reginella" arc by Giorgio Cavazzano features Queen Reginella's planet where a second is worth a day on Earth. It makes its inhabitants getting old in a few minutes when they venture onto Earth.
  • In issue #1 of Universal War One, Balti enters into 'the wall'. His companions wait for him a few minutes outside but when he comes back almost dead, he spent 3 days inside.
  • In a Captain America storyline, the title character gets on a mysterious subway and is pulled into Dimension Z, run by his nemesis Arnim Zola. After spending over 10 years in Dimension Z, during which time he kidnapped Zola's son and raised him as his own, his girlfriend Sharon Carter shows up to rescue him. He'd only been gone for 10 minutes in the real world.
  • In Birthright, the main protagonist is a young boy from Earth transported to a fantastical realm known as Terrenos. He spends many years living there, training as a warrior and growing up into adulthood. When he returns to Earth, he finds that only just one year had passed.
  • Pathfinder: Worldscape: The Worldscape is a demiplane where time moves slower than in other places, and people trapped can live for decades in there, but age slower than they would in real time. When Merisiel is dragged from her home to the Worldscape she spends many days there, but when she is returned, its revealed she was out for only 10 minutes.
  • In an three issue story arc of Fantastic Four, the Four and the Avengers try to rescue Central City which had been encased in a black dome. Iron Man goes inside with the panel showing him entering and exiting in virtually the same instant. Tearing off his helmet, a bearded and ravaged Tony Stark talks about how he almost exhausted his energy and food packs and demands to know why no one came after him. Told he was gone less than a second, he's stunned as to him it was almost three months.
    • She-Hulk is drawn in accidentally, followed within minutes by the Fantastic Four. Inside the dome, the FF discover a futuristic city peopled by strangely evolved people, many of whom have super-powers similar to their own. They eventually discover the creator of the dome was a scientist who was so afraid of nuclear war he created the force field that surrounds the city and which was supposed to slow down time inside it, so that the city would pass into a post-nuclear future in only a few subjective hours - but unfortunately he apparently dropped a minus sign somewhere.
  • In The Unstoppable Wasp, Nadia has a special Microverse-based lab tucked away inside a pendant. In this area, minutes end up being hours. This proves to be a bad thing when Nadia suffers her first major Manic episode following A.I.M. attacking her scientific team G.I.R.L. and she becomes incredibly irritable and sleep-deprived to the point where she attacks said group when they try talking her down. And even worse when one of the group, Priya, chases after her and barely stops her from taking her life.
  • The Ultimates: The City that The Maker designs in the latest series is one big ball of paradox, while it exists in the present, within its walls generations pass while Reed was expanding it with the outer edges closer to normal time. While inside its walls, time moved at an accelerated rate the closer one got to the Core, so as one moved within the City's limits the further into the future it traveled until the City stopped expanding. Which it wound up taking out Germany and a good chunk of Europe when they reach its current size.
  • Wonder Woman (1987): In "The Contest" it's revealed that in the months since Themyscira's apparent destruction due to Circe's magic it was actually transported into another dimension where the Amazons have spent ten years fighting demonic monsters for survival before they were able to return. This also allows the fourteen year old idealistic Artemis to grow into a hardened twenty-four year old soldier with little understanding of the nuances of the outside world.
  • Doctor Who Expanded Universe: In the comic story "The Dogs of Doom," a werewolf-infected Doctor throws the TARDIS into a temporal limbo, where he spends nearly a month working on a way to cure himself. Upon curing himself and returning, his companion Sharon marvels that he did it within a few minutes.

    Comic Strips 
  • Phoebe and Her Unicorn: When Phoebe doesn't do her spelling homework, Marigold helps out by sealing her inside a "magic time bubble" where she can spend an hour studying while ten minutes pass in the outside world. While Phoebe mentions that "It's hard to memorize spelling words when [she's] floating in a timeless void", she gets used to it.

    Fairy Tales 
  • "Mother Holle": The widow's stepdaughter stays in Mother Holle's realm for an indefinite amount of time (several weeks, at least). When she returns home through a dimensional gate, she finds that barely any time has passed back home.

    Fan Works 
  • Alone, Together: Apparently the time lines in different universes aren't necessarily synchronized.
  • In The Blue Dragon, one year in the Dragon Realms is equivalent to one week in the human realms.
  • In Breath of the Wild, the Sheikah tribe train for combat by astral projecting into a spiritual realm where they learn directly from their ancestors, who adopt the form of Sheik. They can spend hours training in this realm while barely a few minutes pass in the real world.
  • The Bridge:
    • Rodan falls through a portal and lands in The Shimmerverse, leading to the spinoff The Bridge: A Shimmer in the Dark. After spending a day there, he returns and it turns out no one even noticed he was gone, as only about a second had passed.
    • Grand King Ghidorah can use his Gravity Master powers to create areas where time flows differently. When this ability is introduced, he uses it to spend a lot of time meditating while on a strict deadline.
  • In Child of the Storm, this is a perennial hazard of visiting the Nevernever, where the rate of the passage of time varies from more or less one-to-one to centuries passing relative to an hour of normal time. This becomes particularly significant in Ghosts of the Past when it transpires that the Red Room has a base in the Nevernever, and as a result, the twelve days that Harry spends in their hands equates to over six months - more than enough time to transform him into the Red Son, the successor to the Winter Soldier, and use him to subjugate half a continent.
  • The Hyperbolic Time Chamber of Christian Humber Reloaded has a year pass inside for every day that passes outside. Vash trains for 10 years in the 10 days before the start of the Ying-Yang War.
  • In Dragon Ball Z Abridged, the Hyperbolic Time Chamber is used as is it was in canon. However, here, Mr. Popo can change the flow of time however he wants. He uses it to troll Vegeta, making him snap under the pressure in only a few hours. Inside and outside.
  • In The Elements of Harmony and the Savior of Worlds, time in the world of the Little Ponies fell out of sync with time on Earth when the Rainbow Bridge collapsed. So while only twenty years passed for Megan, fifteen hundred passed for Equestria. The flow of time is synchronized once more, now that a new connection between the worlds exists, so there won't be any further problems.
  • At one point in For Love of Magic, Harry develops a chamber where time passes one hundred times faster within than in the normal world, which he calls a Hyperbolic Time Chamber. Harry overuses it to such an extent that, combined with unthinkingly aging himself five or six years with runes, he's physically 40 by the time he turns 25.
  • Friendship Is Magic: The Adventures of Spike: Spike's conversations with Dreamy inside his mind play out like this. She says they're speaking at "the speed of thought", which is apparently pretty fast.
  • In the Ghostbusters/Danny Phantom crossover "The Ghost Child and the Ghostbusters", at one point the Ghostbusters and the Fentons find themselves needing to assemble a wide range of equipment to face Morbius, who has absorbed the power of several ghosts and turned them into essentially his brainwashed army. Recognising that they need aid, Clockwork visits them in Fenton Works and essentially freezes time outside the base so that the Fentons and the Ghostbusters will have time to complete their work before facing Morbius again.
  • In Guilty Sparks, it's established that while Commander Shepard and company have been in the Halo universe for barely two months, only a week has passed back home, with an additional week passing in the Mass Effect universe in-story. They are able to communicate via an interdimensional relay with no obvious problems later in the story, however.
  • Hearts of Ice: Akane gets exiled to the Kami Plane and spends nearly seven years fighting demons. When she finally returns to the human world, only weeks have passed since she got trapped.
  • In Hell Is a Martial Artist, Nabiki is sent to Hell for violating her contract with Hild. When Hild later decides to make Nabiki into Ranma's slave, only one day has passed on Earth while Nabiki has been tormented for decades, to the point she needs time to remember who Ranma is.
  • Discussed in Hellsister Trilogy when Supergirl wonders how much time of her life she's spent in the future given how often she time-travels to meet the Legion of Super-Heroes.
    Briefly, she wondered how much of her life she'd spent in the 30th Century. Linda guessed that, if she took that time into account, she could probably celebrate her birthday six months early. Well, at least she could return in time to only a few seconds after she departed. That way she wouldn't be late for work.
  • In Hope on a Distant Mountain, the events of Danganronpa: Trigger Happy Havoc occurred in a virtual reality Unwinnable Training Simulation. To Naegi, it felt as if about three weeks passed. In the real world, it lasted about as long as it would take to complete a playthrough of the game.
  • In the Kick-Ass fanfiction "Impending Nuptials," Big Daddy explains to Hit-Girl that for every day one spends in Hell, only 1 hour goes by on Earth, and that one's time spent in Hell is sentenced in Earth years.
  • In The Keys Stand Alone: The Soft World, almost six years have gone by on C'hou during the intervening ten weeks on Earth, and when the four are sent back they're stunned by all the changes. Mindful of the time, they vow to do whatever it is they're supposed to do in no more than a month so only a day goes by at home. They're pretty dismayed to learn that things are likely to take six months to a year to accomplish.
  • The Time-Compression Chamber in the Great Palace in the Harry Potter fic King of Kings, Ruling over Rulers allows this.
  • In Kyon: Big Damn Hero, Yuki's nightly training for Kyon, Kanae and Mikuru involves a Year Inside, Night Outside Pocket Dimension.
  • Land Before Time Retold: Time passes by more quicker in the Land Before Time than in the human world. Within the first two chapters, Littlefoot hatches and ages five years while only five days pass by in the human world, and when Original Character Aylene finally returns home after being in that world for several days, she's shocked to discover she was only gone for five minutes.
  • This is the nature of the Vytal Festival leadership simulation in Lords Among The Ashes. For every year spent in the simulation, only one day passes for those outside it. Once the simulation is over, the participants' Auras age them to their in-sim forms as that is what they recognize as their body's natural state.
  • In Naruto: the Secret Songs of the Ninja, time spent inside Naruto's soulspace where the Kyuubi is imprisoned takes no time at all (since it's not a real physical space), allowing Naruto to mentally enter it to deal with the Kyuubi and emerge from it again mere seconds later.note  Interestingly it also works the other way around as well if Naruto is dragged in there while unconscious- while he can spend only a few minutes or hours in there, regardless of when he leaves he won't return to his body until it wakes up on its own, no matter how long that takes.
  • In Neither a Bird nor a Plane, it's Deku!, K.E.L.E.X. places Izuku's mind in a hyper-accelerated virtual reality simulation that moves far faster than it does in real time. By the time the simulation finishes, All Might has barely finished a sentence in what felt like hours to Izuku.
  • Outsiders (xTRESTWHOx): Arceus has Dialga alter the rate that time passes on Earth for the duration of Louise's test. She spends a year on Earth but only a week passes on her homeworld.
  • The Pieces Lie Where They Fell: Chapter 26 of the sequel, Picking Up the Pieces, reveals that Tartarus is subject to this, at a month-inside to day-outside ratio.
  • In the Power Girl / Buffy the Vampire Slayer crossover Origin Story, when Alex Harris finally returns to the "Buffy" universe she finds that while only a year passed for her while she was in the Marvel Universe, three years have passed for Buffy and her friends.
  • In The Portal, six weeks in the Dragon Realms is equivalent to a few days in the Human World, as explained in Chapter 5 of the sequel, Hard Choices.
    John: What have you gotten yourself into the last few days?
    Blizzard: Dad, I've been like this for almost six weeks.
  • The afterlife in Resonance Days has this going on. Mami has been there for seven years, despite having died less than a month prior to the story.
  • Discworld fan fic Slipping Between Worlds averts this trope twice. Firstly, nobody is actively looking on Earth for eight missing people, as they have all been seen to perish in such a massive bomb explosion it is presumed to have vaporised them. However, several million-to-one chances have coincided to flip them into a different plane of reality, which turns out to be the Discworld. And because of HEX the supercomputer, time on the Discworld flows parallel to time on Roundworld (Earth). Leading character Philip Holtack thus gets to be a guest at his own funeral.
    • In the same author's crossover Discworld and The Big Bang Theory tale, The Many Worlds Interpretation, as the days and weeks go by in Pasadena, visiting Discworlder Johanna wonders about how to explain her eventual return to Ankh-Morpork, in winter, only several apparent minutes after she departed - with a sudden overnight Californian suntan.
  • In Rider Time Zi-O: Roze from Remnant, Ruby Rose spends a whole year in the world of Sougo Tokiwa, only four four days to have passed in Remnant when Ruby returns home.
  • In Shadows and Light a week in the demon realm is equal to a day in the mortal world.
  • Felix, in Spellbound, attends a revel in a faerie mound, where time passes strangely. Trees grow up around him and bear fruit within seconds, and animals seen in the corner of his eye are piles of bones by the time he looks at them directly. And that's just the front entrance.
  • Take a Stand: The Broken Mirror:
    • One day in the mammals' dimension equals 9½ days in the humans' dimension.
    • The Tempus dormitory, where Kodi Jones begins training in the Mystic Arts with Doctor Strange. While he trains for a whole year, outside it's just about six hours.
  • As The Teacher of All Things takes place in the Adventure time line the above holds. However we also get another plot point for the time curve, six months—the time from the events of V-Tamers to the events of the story—in the human world is equivalent to 2000 years give or take.
  • At the beginning of This Bites!, just before sending Cross to the One Piece world, B.R.O.B assures him that in order to avoid all the melodrama of people missing him, upon reaching the end of the story, he'll return to the exact moment he left.
  • Titania Falls: One year on Earthland translates to forty-five years on Earth. When Fairy Tail's Tenrou Group reunites with Erza four months after her "death" at the Tower of Heaven, they find that it has been fifteen years for her since she last saw them, during which she has made a life for herself on Earth, newly divorced and with two preteen children to raise. The temporal dissonance isn't rectified until Hibiki and Ford permanently bridge the two dimensions together.
  • Warband of the Forsaken Sons, a Warhammer 40000 fic, has an example where an entire world, thanks to being plunged into a Warp Storm and cut off by a curtain of eternal night, doesn't follow the time of the rest of the system. A Chaos Marine on the planet spends generations preparing the recruits for his masters, while only months pass outside.
  • In Webwork, Jade escapes into a demon netherworld where a year passes for every hour in the human world. Eight hours of her family and Section 13 trying to find out what happened to her, the now 21 year old Jade emerges back into the human world as a humanoid spider yokai/oni hybrid.
  • Time flows differently in the various universes that the four main characters visit in With Strings Attached:
    • When they go to the Hunter's world for six days, then discover that a month passed on C'hou while they were gone. More pleasantly for them, after having spent some four months on C'hou and terrified about what they'll be facing when they get home, they learn that only four days have passed on Earth. Though the Fans "soothed" the people close to them, the news inevitably leaked out. Still, only four days means they're able to explain away their absence by pretending to have gone on a little secret vacation together to reestablish their friendship. It is still a bit awkward, as the world watched the ex-Beatles disappear for four days.
    • While the Hunter has been on the world Armia for some 20 years, Jeft talks about having him for five years.
  • Worm Grand Order: Taylor Herbert gets Stuffed into a Locker by bullies, then is ubruptly transported to Chaldea, where she becomes its only Master and works with her Servants to fight the Singularities. After 3 years, she finds a way back to Earth Bet, only to find a few minutes had passed there. Her father is shocked that she is now a battle hardened grownup.

    Films — Animation 
  • Neverland from the Disney version of Peter Pan. The Darling children and Peter Pan arrive there at night and spend one day there, then return to London the following night. But when they get back, it's still the same night as when they left, and their parents never even notice that their children were gone! Averted in the original play and book, however, where the children come back to find their parents distraught by their long absence.
  • In Legends of Oz: Dorothy's Return, the Tin Man and Lion talk about how it's been years for them since Dorothy was in Oz, but the Scarecrow comforts them by saying for her it'll have only been just yesterday.
  • Wonder Park: The protagonist June Bailey returns home after being away thirty minutes (noted by her father) despite being in Wonderland for almost a whole day.

    Films — Live-Action 
  • In Contact, Dr. Arroway's trip through the Portal Network, conversation with an alien, and return home seemingly took about 18 hours. But as it took less than a second as time is reckoned here on Earth, quite a few people ended up strongly doubting that she actually traveled anywhere at all, since no one on Earth saw Arroway's pod disappear and her recording equipment displayed only static. Then, at the end, the technicians realize that her recording equipment recorded 18 hours of static.
  • In Cube 2: Hypercube, the main characters' stay in the hypercube appear to take place around several days. When Kate emerges on the outside, the Hypercube collapsed in 6 hours, 6 minutes, 59 seconds in real world time. To complicate things, time is relative inside it even among its occupants and some are stuck for what literally appear to be years.
  • The Forbidden Kingdom: The hero is magically transported back to Ancient China and goes on a quest to save the Monkey King and defeat the Jade Warlord. He is then granted his wish and is returned home on the exact moment and location of where he was before the journey began.
  • Freaks (2018): Henry has the ability to create a bubble in which time moves much faster. In combat, he uses this to create situations of Super-speed. He also uses it to give Chloe seven and a half years of growing up in the few months since she was born.
  • Inception: An hour-long dream spans five real life minutes. But a dream begun within that dream can last an entire day. Start another inside that and it will last a year. If you're stupid and/or desperate enough to go even deeper, get ready to spend at least a few centuries with nothing but your nightmares for company. This is demonstrated in the film when Dom and Mal are trapped in limbo for fifty years, waking up only a few hours after they fell asleep when they finally escape. There's drugs that make that gap even wider.
  • The director's commentary for Pleasantville explains why Jennifer can spend 4 years in college in the TV without mom worrying about her — since the Pleasantville TV show aired for half an hour a week, a week in Pleasant-time passes in half an hour of real time. A month lasts two hours, a year, two days. (This is made clear in the movie as well. David and Jennifer are clearly there for some time but when David returns to the real world the TV says that the Pleasantville marathon has been on for an hour.) Specifically, it appears David was in Pleasantville for at least four months while exactly one hour passed back home. (They arrive in April 1958, and he leaves just after seeing Jennifer off to college, meaning it's probably August in Pleasantville.)
  • TRON:
    • Although not referenced directly in the first film, Jeff Bridges spends what seems to be several days inside the computer world, only to emerge on the same night that he left. It's unknown how long this was in the real world, but it was long enough for Alan to go to his computer and upload a file to Tron.
    • It's pretty much confirmed in the video game sequels; there's a part in the Game Boy Advance game TRON 2.0: Killer App where a program named Mercury asks an older program called FAT2NE to decrypt a crucial data file. FAT2NE responds that the process could take "several seconds", with Mercury's response being along the lines of "We don't have that kind of time!"
    • In the sequel, TRON: Legacy, it's confirmed that time passes 50 times faster in the computer world. So while Kevin Flynn (Jeff Bridges) has been missing in the real world for 20 years, he has lived 1000 years in the computer world.
    • In the first film during the Solar Sailer/Recognizer encounter, Yuri claims the next beam is a few nanoseconds away; in context, this is understood as meaning minutes (not a long amount of time but too long to wait in an emergency), thus leading to Flynn's reveal as a user. Since Flynn's chair never fell over, it can be assumed that he was on the grid less than 1 second, since the timescale of 1 real world second = 1 billion Grid minutes = ~1900 subjective years for Flynn. The 20 years in the sequel is even worse.
  • Marvel Cinematic Universe:
    • In Thor: Ragnarok, Hela chases Thor and Loki into the Bifrost's portal. She knocks Loki out of it, then Thor a few seconds later. Thor lands on planet Sakaar and eventually runs into Loki. Much to Thor's confusion, Loki has been there for weeks.
    • Shown in Avengers: Infinity War, Dr. Strange uses the Time Stone to travel to over 14 million possible futures to see if they can beat Thanos. While he returns to the starting point on Titan, he still experiences the equivalent of almost 40,000 years (using one day per future as a guide).
  • This is part of the eponymous technology in OtherLife, where the memories/dreams created by the nanotech only take a minute or so to experience, but mentally feel like days or even years.
  • 1408: Time is one of the many things that don't function normally in room 1408. At one point Mike is lulled into thinking it was All Just a Dream, and he goes on with his life for about a week on the "outside" before the room reveals that he never left at all. In truth, he barely spent an hour in there.

  • Aeon 14
    • In the Intrepid Saga trilogy, it's legally mandated under the Phobos Accords to establish "expanses" where sentient AI can be raised in the same way that humans are. These expanses are processor-clocked so that time passes faster inside than in the real world.
    • In The Last Bastion of Star City, Jessica, Iris and Trevor voluntarily spend two decades from their perspective inside a Lotus-Eater Machine birthing and raising AI "children" as defenders of the eponymous Dyson Sphere and its billions of inhabitants, who are inside similar computer-generated worlds attempting to achieve ascension. Only two days pass in the real world.
  • The Colonial Marines Technical Manual for the Alien universe indicates that starships undergo "time expansion" during FTL Travelhence the need for hibernation pods.
  • Phaze Doubt, the final novel of Piers Anthony's Apprentice Adept series, notes that each of the four poles of Phaze contains a cave in which time flows differently by a specific factor. Three are this trope while one is the reverse: Year Outside, Hour Inside.
  • Artemis Fowl: In The Time Paradox, Artemis and Holly spend about three days in the past while for Foaly and No.1, it was only ten seconds. It's played for laughs at the ending of the book and doubles as Leaning on the Fourth Wall from the reader's point of view. We see Foaly beginning to count from one to ten, see the entire journey of Holly and Artemis, then "return" when Foaly say it's the longest ten seconds of his life.
  • Some stories by Stephen Baxter take place in a world where time moves faster at higher altitudes.
  • In Ursula K. Le Guin's The Beginning Place, heroes Hugh and Irene are able spend a week or so in the Evening Land while only being absent from their usual lives for a single night.
  • A cruel variation of this happens to the protagonist in Gene Wolfe's short story A Cabin on the Coast. He makes a deal with a supernatural being to come back to the real world just after he left it, but the catch is that he has aged and his fiancée doesn't recognize him.
  • Similarly, in a crucial fight scene in the Callahan's Crosstime Saloon series, Mick Callahan is able to formulate a plan against an attacking alien by flickering in and out of different time periods rapidly, appearing to remain in the bar while he actually takes years of preparation. Carefully; like in Doctor Who he can't go back to where he was before.
  • In Roger Zelazny's The Chronicles of Amber series, time in one Shadow can pass at just about any rate relative to another. They play with this trope very explicitly: whenever one of the Amberites or Chaosites needs more time for something and can afford to leave for a while, they simply Shadow-walk or Trump to a place where time runs slower.
  • The Chronicles of Narnia is probably one of the most well-known examples of this trope. In The Lion, the Witch, and the Wardrobe, Lucy disappears into Narnia for hours, but when she worriedly returns home she finds that she was barely missing for a minute. Then when all the children go through, they remain there until adulthood as the Kings and Queens of Narnia... only to return home, find themselves young again, and discover that only minutes have passed. Then, in Prince Caspian, they discover that hundreds of years have passed in Narnia since their last visit. It's only been a year for them. However, the ratio isn't remotely consistent; see Narnia Time.
  • The Chronicles of Thomas Covenant has a 1 year = 1 day ratio between the Land and the "real world". It is made ambiguous by the ongoing mechanic in the novels, that upon entering the Land Thomas Covenant is completely healed (by various means) of all hurt save for his ongoing disease. Before he leaves, however, events in the Land must transpire as to return his newfound health to exactly the same state it was when he entered the Land, usually giving a ominous foreshadow as to what's to happen in the novels. In the second trilogy, Covenant is stabbed on a sacrificial rock before entering; we then know (as does he - it's of concern to him throughout that trilogy) that he will die when he leaves the Land again. Likewise, In the third series, both Linden Avery and her son Jeremiah are fatally shot before entering.
  • Iain M. Banks' The Culture: The virtual reality Hells of Surface Detail all make use of this trope, to maximise the suffering of those condemned to them. Chay, an academic on a factfinding mission, becomes entrapped in the Hell she is investigating. In the real-time weeks of the novel, she lives out an entire lifetime first as a nun in a convent, spending decades in quiet contemplation and recovery from her earlier trauma. After her second encounter with the Master of the Hell, she becomes an Angel of Mercy, travelling the Hells freeing souls from their torment, at the cost of her own suffering.
  • Discworld:
    • Death's realm is an extreme case. It's a Pocket Dimension which doesn't have actual time, just something Death made that seems like it. His manservant managed to stay stuck in his 60s for 2000 years.
    • In the first The Science of Discworld, time within Roundworld passes so rapidly that many millions of years go by every Discworld day.
    • In later books, HEX demonstrates he can control the flow of time on Roundworld, speeding, slowing, or rewinding it down alternate different pasts and futures as is necessary.
    • In Wyrd Sisters The Witches of Lancre manage to create a disparity in time between Lancre and the rest of the Disc of seventeen years: this allows the presumed heir to the throne to grow to maturity in Ankh-Morpork, whilst giving the usurper no time to prepare defences against his return or contract an Assassin to deal with the problem. Lancre is effectively stuck inside a time stasis for seventeen years.
    • In Witches Abroad, it's used by Lilith to freeze an entire castle for a hundred years, after a princess pricks her finger on a needle...
    • The History Monks in Thief of Time are shown to be able to "slice time": basically create narrow temporary paths of the trope that allow them to move quickly relative to real time. The better one can slice, the higher the time compression ratio.
  • In Dragon's Egg, the cheela experience time a million times faster than humans do. They go from a pre-industrial civilization to having explored the galaxy with FTL starships in twelve hours. This plot was later loosely adapted into an episode of Star Trek: Voyager.
  • In Everneath by Brodi Ashton, Nikki goes with Cole to The Underworld, called Everneath, where he drains her Life Energy. It feels like they have been there for hundreds of years, but it ends up only being 6 months in Earth-time.
  • In Greystone Valley, Sarah returns home after several days only to find that it has been an hour since she disappeared.
  • In the Guardians of the Flame series, for every earth hour that passes, four to five hundred hours pass in the other world, hence not being seen for a weekend on earth means up to four years of life you can spend there.
  • In "The Gypsies in the Wood", a brother and sister are snatched away by The Fair Folk, and when the boy reappears three days later he's aged nearly thirty years. The girl is away for considerably longer, and when she's about to be returned the protagonist briefly worries about how old she'll be, but in the end she's aged about as much as her brother. The story allows for several possible explanations, including that she was in suspended animation for most of the time after her brother escaped, or that the passage of time in the fairy realm doesn't have a direct relationship to the passage of time in the normal world. Another hint that it's not a simple case of "time passes quicker there" is that when the boy returns he's lost a tooth and is growing another, which the examining doctor notes is normal for a boy the age he was when he disappeared but unheard-of in a man the age he now appears.
  • In the Kadingir series, Earth is connected to a parallel dimension where time goes seven times as fast, making it Week inside, Day outside. This allows The Heroine to go on adventures for months on end while her parents think she's spending the summer hollidays abroad with her grandmother.
  • Works of Peter F. Hamilton:
    • In the Night's Dawn sci-fi trilogy, the Commonwealth has "zero tau" fields, inside which time is simply switched off — except for the space zombies from another dimension, who still experience time inside, but since their hosts don't, it's effectively massive sensory deprivation torture to them. Just about the only way to exorcize folk unlucky enough to get possessed.
    • The titular Void from the Void Trilogy has time pass more slowly within it (specifically a year inside corresponds to a day outside) as is heavily implied throughout The Dreaming Void (as there's no way the implied Void timeline could be reconciled with the Commonwealth timeline if they moved at equal speed) and confirmed in The Temporal Void when a character from the Commonwealth enters the Void itself. By the time of The Evolutionary Void, more than one species/characters are revealed to have essentially weaponized this idea.
  • In The Hazel Wood, years pass in the Hinterland (a fairy tale realm) while almost no time passes in Real Life.
  • Works of Robert A. Heinlein:
    • In The Number of the Beast, a universe spanning device also allows you to visit universes which experience time on an axis 90 degrees to our own. This means you can spend any amount of time there and no time will pass in your own universe. Unusually for this trope, the main characters' first idea when this ability is discovered is that they could make a business off it. (Selling a week not in the calendar to students with a final exam coming up...)
    • In The Puppet Masters Heinlein also featured a drug that could do this somehow.
    • In Tunnel in the Sky the same technology that allows for instantaneous interstellar travel enables people to create zones where time moves relatively faster or slower than the outside world.
  • "House of If" by Barry B Longyear features a device allowing a prisoner to subjectively serve a 20-year prison sentence in 5 minutes of real-world time.
  • Whenever the children in In the Keep of Time return from traveling through time, they find themselves outside the tower door at the exact time they left.
  • In Johannes Cabal the Necromancer Cabal goes to confront an evil sorcerer, Rufus Maleficarus and his small band of lunatics-mostly cause they're in his way. However Cabal is so unafraid of Rufus that he mocks him and lets him chant a spell that eventually (while Cabal waits, taunts and sneezes) tosses Cabal into a pocket dimension. The place, known only as the Garden, seems to have no time, or death, though to Cabal he's there for a few minutes at least (which is more or less meaningless in a world without time-until he makes some) but when he comes back its noted in the narration that he's been gone-to the outside world-for thirty seconds.
  • The House in the Keys to the Kingdom series runs awfully conveniently. Each of the Trustees can only affect the real world on their day of the week. The main character may spend several months, or slightly over a day, in a single section of the House, but less than a day will elapse in the "Outer Realms". So with luck, he's going to take control of the entire universe in a week. The convenience in the time of the outer realms starts going out of whack in the fourth book — half a day has passed while the protagonists were in the house, and in the fifth book, it is revealed that Arthur has now spent a week in the House during the time passed in the fourth book.
  • In Octavia Butler's Kindred:
    • Dana's flashbacks last anywhere from a day to eight months, but in the present she's only gone for a few hours at most.
    • Kevin, her husband, gets left behind in the past. Dana spends a few weeks in the present waiting for a chance to go back and rescue him, and when she finally does, he's spent five years in the past.
  • Milo's journey through the The Phantom Tollbooth takes several days to his perspective, but when he returns home he finds it is only sundown.
  • Stephen King:
    • The short story "The Jaunt" revolves around a method of near-instantaneous teleportation. The catch? You have to undergo anaesthesia before doing it. If you don't, to your mind it'll seem like it's taking forever—literally. To quote the story; "It's eternity in there..." Needless to say, people who undergo Jaunts awake end up completely batshit insane, not to mention suicidal.
    • 11/22/63: No matter how much time you spend once you go into the Portal to the Past, you'll always come back out exactly two minutes later than when you went in.
  • Many of Larry Niven's Known Space stories include "stasis fields" that slow down time inside them, but one featured a field that sped up time. It was used to commit a murder (a flashlight inside the field became a deadly energy beam outside as several hours of output was concentrated into a split second) and then cover it up.
  • In The Last Bastion of Star City, Jessica, her boyfriend Trevor, and her AI partner Iris voluntarily spend 18 perceived years inside a Lotus-Eater Machine raising AI children as defenders of the eponymous Dyson Sphere and its inhabitants. Two days pass in meatspace.
  • In The Legendary Moonlight Sculptor, when players connect to the VRMMORPG, the author describes the players as experiencing a time parallax. The game experiences time as flowing four times as fast. So while the game has only been released for a year after the story's introduction is done, the game itself has had four real years. This becomes more important as a media group is trying to edit footage from the game, and is unable to keep up with the "live" footage, having to frequently fast forward.
  • In The Midnight Ground Abby helps Helena return from the dream realm. In the waking world, about fifteen minutes pass, but Abby and Helena experience a three year journey to escape.
  • Used as a means of interrogation in the cyberpunk books by Richard K. Morgan — as time in virtual reality can be sped up the lengthy torture needed to break a professional or fanatic can be over in a short time, enabling the information to be obtained quickly. In Broken Angels the protagonist gets one man to talk by trapping him in a very plain VR environment and threatening to leave his physical self in a place where no-one will find him for a very long time — with months passing like years he would quickly go insane.
  • Mythago Wood: The deeper into Ryhope Wood you go, the stronger the effect will be, and the wood is Bigger on the Inside, so you can go very deep. One character is inside for fifteen years while eleven months pass outside. At the deepest part of the wood is Lavondyss, "where the souls of men are not tied to the seasons."
  • The Neverending Story
    • Atreyu spends what he feels is just less than a day at the Southern Oracle but actually a week has passed for everyone outside the Oracle, though it is slightly averted as time did pass for Atreyu as he notices his wounds are significantly healed.
    • Bastian spends 100 years in Fantasia while only about 12 hours pass on Earth.
  • In David Drake's Northworld trilogy, an exploration team went to a newly discovered world ... and vanished. Another team went, reported the world safe for colonization ... and didn't come back afterward. Colonists went ... and then all contact was lost. The Consensus sent three massive fleets to investigate, one after the other, and each vanished. Then the Consensus got serious and sent protagonist Nils Hansen. This all occurred over the course of a few years. For the explorers, colonists, and fleet crews (or their descendants), it's been roughly ten thousand years. Also, Northworld consists of nine interlinked universes — and time spent in one world has no relation to the passage of time in another: you could transfer out of one universe as a bullet flies toward you, spend years flitting about the other eight, and finally return to the first while the bullet is still in flight.
  • In The Pendragon Adventure: Black Water, Mark and Courtney go to Eelong to help Bobby and spend several weeks there. Before returning, they wrack their brains for a plausible excuse of where they've been, then discover they've only been gone for half an hour.
  • In the Peter Pan books, time is slowed, but not by a lot. Peter has to keep leaving Neverland to find more Lost Boys, or to ditch them when they become too old.
  • In the alternate universe time traveling story, The Proteus Operation, Albert Einstein is stumped when he can't communicate with the future until he reads a story by young Isaac Asimov and realizes that time flows differently between the time periods.
  • Ra: Time flows differently in Tanako's World. You could spend an arbitary amount of time in it during a fraction of a second in real time.
  • The Red Dwarf novel, like the show, deals with Lister, Rimmer, Cat and Holly's adventures after Lister spends 3 million years in a Stasis field that is impenetrable by time. The sequel Better Than Life includes an original plot thread in which Lister is stranded on a planet and ages about 50 years while almost no time has passed for the crew. At the end, Rimmer sends him to the Backwards universe after his death and cremation! to reverse the ageing process.
  • The Reunion With Twelve Fascinating Goddesses:
    • Time in the other world flows at around ten times the rate of Earth.
    • La Shii's Shrine also has this property, fitting her nature as the Deity of time and space. Tooi used this in the past to train himself.
  • In Santa Steps Out, Santa can deliver gifts across the world by being in a type of time bubble. Turns out it has other uses if you know what I mean.
  • In John Niven's book The Second Coming, a day in Heaven takes about fifty-seven Earth years. As such, when God goes for a week off in 1609 at the height of the Renaissance, he returns in 2011 to find the planet falling apart.
  • Pamela Dean's The Secret Country books avert this. Any time spent in the other world is equal to time passing outside. However, a huge amount of text is devoted to the children's various attempts to fix this problem. The solution has some pretty bad consequences, which you don't find out until much later. They are quite annoyed by it all. As Ruth observes, in books they've read things are better arranged.
  • Works of William Sleator:
    • In the book Marcos Millions, the titular Marco goes on a mission to save a pocket dimension. About halfway through his mission, his sister telepathically contacts him to say goodbye. When he finishes and comes out, he discovers she died several years ago.
    • Marco continues using time-slowing devices in the sequel The Boxes, where it's remarked it seems like he never ages. It turns out he spends weeks at a time in the effects of slow time, so for him the last few years have only been months.
    • The book Singularity has a character PURPOSELY put himself inside a shack on top of a singularity's exit (meaning time is sped up, rather than slowed down), accelerating time so he can become older than his twin brother.
  • This applies to the fairy realm in The Shadowhunter Chronicles. Time runs very differently there, and it varies from place to place. If one get into the fairy realm, he can spend a day there, while many years pass in his world, and vice versa. Because of this, shadowhunters are often warned not to get involved with fairies.
  • In The Southern Reach Trilogy, time passes faster inside Area X, first hinted at by the speed at which nature reclaimed the human structures in the area and finally confirmed in Acceptance. Grace spends three years inside Area X even though only a couple of days have passed outside it.
  • In A Star Shall Fall by Marie Brennan, the London faerie court uses Britain's shift from the Julian to the Gregorian calendar (which meant skipping eleven days) to build a room like this. Anyone who goes in and locks the door will come out eleven days later from the perspective of the outside world, no matter how long they view themselves as spending in it.
  • Star Wars Legends: In Galaxy of Fear: The Nightmare Machine Tash and Zak go into the titular machine and experience an increasingly tumultuous remainder of the day, night, and some of the next day before they are able to end the simulation. They find that it's not a machine but a weird psychic monster, and that they'd been under its influence for only an hour.
  • Charles Stross:
  • In Summer in Orcus, Summer doesn't know whether this will apply to her sojourn in Orcus, and worries for a while about how her mother will react if it doesn't, before deciding that there's nothing she can do about it and she'll just have to deal with it as it comes. In the end, it turns out that the witch who sent her on the quest also cast a spell to bring her back immediately after she left, and her mother never even notices she was away.
  • Tempest: A Novel When Jackson half-jumps back in time, if he's gone for 20 minutes, he turns into a vegetable for about 2 seconds. This apparently applies to any injuries he sustains while in the past as well. Getting hit by a car and getting a broken leg results in a bad bruise, and a bad burn results in a small red mark. This is explained as "the God of Time being super OCD like [Adam] and wants the world to be symmetrical."
  • The main characters in Madeleine L'Engle's Time Quartet arrive back home after long travels through space and/or time at about the same relative time as they left.
  • In the Unicorns of Balinor series, fifteen minutes in our world is around a month in Balinor. It's mentioned that there was a rift in time when the Gap between the worlds was formed.
  • Wax and Wayne: In The Alloy of Law, bendalloy mistings can create a bubble of accelerated time around them. Has a variety of uses, from buying a few extra minutes to plan to forcing one-on-one duels with enemy Mooks.
  • In Pam Uphoff's Wine of the Gods series, there are dimensional phenomena called "bubbles" because to someone with the genetic ability to see into multiple dimensions, they appear as translucent bluish spheres. Anyone with the ability to see the bubbles can also grab them and carefully open a small hole in the bubble wall, at which point they can store objects or people (including themselves) inside. As long as the bubble is open, its inside and its outside are in the same dimension and time runs at the same rate. But once the bubble is closed, it is a separate dimension where time runs slower inside of the bubble than outside. The ratio is about a thousand to one, so that one second inside is about twenty minutes outside, and an hour inside is about forty days outside. These bubbles get used for all kinds of things, from storing food to escaping from enemies (duck into the bubble and close it, count ten seconds, and reopen it, and it's nearly three hours later; the people searching for you have long since given up and left). Some of the people with dimensional-manipulation abilities have also learned to adjust the time dilation ratio of the bubbles, taking it from the thousand-to-one default to a one-to-twenty ratio the other way: one hour inside the bubble takes only three minutes outside. This allows getting 8 hours' sleep inside a "fast bubble" while only 24 minutes pass outside.
  • In The Wise Man's Fear, the hero Kvothe enters the Fae realm and lives through months of experiences. When he returns to the mortal world, only three days had passed.
  • Wonder Woman: Warbringer: Time on Themiscyria moves much slower than it does in the wider world. When Diana returns to Themiscyria after her adventure, she finds that barely any time has passed there, and nobody has even had a chance to notice she was gone.

    Live-Action TV 
  • The 4400: Alana's alternate reality projection ability lets her build Inception-esque worlds together with one person at a time, including changing the past, but there is a minor flaw in the worlds she creates that lead back to reality if they are found and the person she shared the dream with wants to go there.
  • In Adventures in Wonderland, Alice's visits to Wonderland seem to work this way. She typically spends hours or even days there, but not much time ever seems to have passed when she comes home.
  • Another Wonderland-inspired example is Alice. The heroine spent about a week in Wonderland but only an hour passed in the real world.
  • Arrowverse: In the first Supergirl/Flash crossover, Barry spends nearly a day on Earth 38 (Supergirl's world) and gets back to Earth 1 mere moments after he left. In addition, the Supergirl episode was aired much earlier than The Flash episode, where he tests the tachyon accelerator and briefly disappears into a portal, only to come back and look around in confusion. The same happens when Barry travels into the past and into the future, with people wondering if he even left, as barely a second has passed.
  • In Ashes to Ashes (2008) Alex spends around three years in The '80s which amounts to roughly three days in the real world. Of course the passage of time in series three is debatable due to all the clocks stopping at 09:06 when she died. Interestingly the timeline in coma and out-of coma for Sam seemed to be the same.
    • Also, whether the relation of time is static or dynamic is up to interpretation - It might depend on the strength of the connection between the real world and the "dream" world.
  • In the Black Mirror special "White Christmas", Greta's AI "cookie" is driven to the brink of insanity by Jon Hamm's character Matt, after she refuses to perform the menial chores required to run the household of her creator. Whilst Matt makes himself a cup of coffee, the cookie is stranded in a featureless white room for six months. After this, she is more than willing to carry out domestic tasks for Greta. It's further revealed by the end of the episode that Greta is not the only cookie Matt has stranded in a virtual reality where time dilates.
    • A later episode, "Playtest", shows that in the end, it's revealed the entire play test only took .04 seconds. Not even the whack-a-mole was real.
  • It's common for different dimensions in the Buffyverse to behave like this. The demon Sahjhan was even able to travel through time by being a master of interdimensional travel.
    • This is the twist in the Buffy the Vampire Slayer episode "Anne." Healthy young adults keep disappearing for a few hours, only to reappear extremely old and confused. Buffy's conclusion: something supernatural is draining their Life Energy. The actual problem: demons are abducting people for slavery in a Hell dimension, working them for decades of its time, and then dumping them back in our world once they're too old to be useful.
    • In Angel, Angel's son Connor was sent to Quor-toth (a hell dimension) and aged from an infant to a teenager in a few months.
    • However, Averted with Pylea: Winifred Burkle was trapped there for five years, in both that world and on Earth.
  • Cloak & Dagger (2018): Ty and Tandy find that Ivan Hess, who appears to be in a vegetative state, is actually trapped in his own mind in a "Groundhog Day" Loop of the last moments before the oil rig exploded. While it has been almost a decade in real life, in his mind he's gone through thousands of years of loops. When Ty leaves Ivan's mind for 30 seconds and returns, Tandy has been through 200 time loops.
  • Doctor Who:
    • "Rose":
      • In the e-book The Beast of Babylon the Ninth Doctor has an adventure after he leaves Rose at the end of the episode. He then returns to Rose, from her perspective, within a minute of him departing. We later indirectly learn in "The Day of the Doctor" that he'd been gone a century from his perspective, the events of The Beast of Babylon being the final outing, before returning to Rose.
      • The 2018 novelization adds even more of this trope to the story by revealing that the Doctor went travelling for several weeks between his encounter with Rose at her apartment and when he saves her from the Auton duplicate of Mickey at the restaurant in the evening.
    • "Aliens of London" opens with the characters expecting this trope, only to discover that it's been subverted and Rose has been missing for a year, complete with missing person posters and a police investigation.
    • "The Girl in the Fireplace": Upon arriving on an abandoned spaceship, the Doctor finds an 18th century French fireplace, which is actually a Time Portal. The first time he looks through it, he speaks to the eponymous girl ("Reinette") who lives in France in 1727. He goes through the time window and Reinette informs him that it was months ago that he last spoke to her a few seconds before. Each time he goes back to the spaceship and returns through the fireplace, years have passed. At the end of the episode, the Doctor tells her to pack her bags and come with him. He runs off to find his companions in the spaceship, in his excitement forgetting about the time differential. When he returns to the fireplace, he finds that Reinette has died waiting for him.
    • This happens to the Doctor and Martha in series 3. From the perspective of an objective observer such as Martha's brother Leo, the events of the entire present day Myth Arc take place over the span of not more than a week. From the perspective of our protagonists, it was at least a year and a half. This isn't even going into Captain Jack and the rest of Martha's family, who remember the Year That Never Was.
    • Done cruelly to Rory in "The Doctor's Wife". Basically, a possessed TARDIS traps Rory and Amy inside of itself, and at one point it begins screwing with them by getting the two separated. For Amy, it's only a few minutes or so, but once she finds Rory again, months have passed for him, and he's terrified he'll lose her again. Then it happens again, and this time decades have passed, he's an old man, and he's gone mad in both senses of the word because he waited for Amy to show up and she never did. Then Amy loses him again and finds Rory dead, a skeleton in a hallway filled with insane scratchings of his plan to get revenge on Amy, and Amy has a nervous breakdown over it. All this is subverted when Rory comes up behind her and asks what's wrong, revealing himself to be okay and the whole thing having been the possessed TARDIS messing with Amy's sense of reality.
    • "The Girl Who Waited" has Amy trapped in a faster timestream. In the few minutes that it takes the Doctor and Rory to figure out how to get to her, 36 years pass for Amy, turning her into a bitter, bitter old woman.
    • In "The Caretaker" (and several other episodes prior) Clara is getting somewhat exhausted because she's having entire adventures with the Doctor in between (and sometimes during) dates with Danny Pink. It's implied the Doctor is doing this deliberately.
    • At the beginning of "Arachnids in the UK", the Doctor returns Ryan, Graham and Yaz to Sheffield half an hour after they were teleported away at the end of "The Woman Who Fell to Earth".
  • In Emerald City, Dorothy spends approximately 10 days roaming through Oz but in the episode "No Place Like Home" when she's sent back to Kansas, she discovers that only ten minutes has passed.
  • Eureka has a similar one. By trying to save Kim through Mental Time Travel, Henry remembers four years that will never happen. Oddly enough, the four years that Henry remembers aren't the same history that Carter remembers when he went back to stop him, since the Henry that travelled back was the one who originally lost her.
  • A Farscape episode features the characters thinking time moves faster on a planet below them when Aeryn returns from it old and with a granddaughter, only to discover that their ship is stuck in an area where time moves more slowly. They eventually have to starburst (hyperspace jump) backwards out of the time bubble, leaving them with no memories of the experience except an instinct to avoid the bubble from now on.
  • On Heroes, Matt Parkman traps Sylar in an empty nightmare world in which he's the only inhabitant. When Peter enters the dream world in order to recruit Sylar's help in saving Emma, he discovers that hours in the real world is years in Sylar's dream world.
  • An inverse is seen in Legend of the Seeker, as time in the Palace of the Prophets flows slower than on the outside. A month inside is equal to a year outside, which becomes a problem for Richard, as the Sisters of the Light want to train him to control his magical abilities (doesn't help that he's the product of the merging of two powerful magical bloodlines) for about 2 years, which would be about 24 years in the outside world. Richard points out that the Keeper will win by that point, but they don't listen. In the next episode, Richard is trapped in the Fields of Perdition and experiences a nightmare, in which he spends several months inside the Palace, only to find out that two new Seekers have been named, Kahlan has married someone else, and the world is coming to an end.
    • In the book, it is an age slowing spell, used because for a sorceress to train a wizard (there are radical differences between their magic) it takes two centuries at least.
  • Season 4 of Lost reveals a time discrepancy between the island and a freighter just a few miles offshore. A payload fired from the freighter lands a half hour late, with its clock half an hour off. Later a corpse washes up on the island before that character is killed on the freighter. This discrepancy has not to date been explicitly mentioned in the dialogue, except when the one character (Faraday) who seems to realize it comments that time is relative.
    • Travel to and from the island to the ship is carefully controlled as the time dilation drives men mad. And even then, it gets a lot of people.
  • Lucifer (2016): Time in Hell moves exponentially faster than it does on Earth. When Lucifer returns to Hell between seasons, only a couple of months pass on Earth but for him it's thousands of years.
  • The Orville has an episode where a planet in another dimension pops into the character's universe every 11 days, but after 700 years pass in the other universe. The main characters accidentally contaminate the planet with a religion based around Kelly the First Officer, and are extremely lucky to have not been stuck there at which point they would have been long dead by the time they came back. A robotic character decides to stay behind for 700 years to fix the damage.
  • In Other Space Mike and Tina are sent down to a planet for a 6-hour initial safety check, and discover that times moves at a rate of one month per hour. While stuck there they get together and all seems well until their beam-up is delayed by twenty minutes above due to a robot revolution. Which is long enough for them to break up, lose their minds, and get beamed up just as Tina is finishing eating Mike's leg.
  • The Outer Limits (1963) did two vaguely similar examples of this trope. Adding to the similarity between the two stories, actress Nellie Burt plays a sinister, gossipy harridan in both episodes:
    • "Don't Open Till Doomsday" starts in 1929, when a groom on his wedding night becomes trapped inside a box with a nihilistic alien who wants him to help destroy the universe. The groom refuses and winds up spending 35 years inside the timeless void of the box, remaining young while his bride becomes a crazy old woman.
    • In "The Guests", an idealistic young drifter becomes trapped in a mansion which has been taken over by an alien brain who is studying humanity. Time doesn't pass inside the house, and No Immortal Inertia means the other people confined within (who have all been there for decades) can't leave.
  • In The Outer Limits (1995), there's an episode called "The Sentence" where this trope is used for a prison.
  • Red Dwarf: In "Rimmerworld", the escape pod Rimmer was in ended up flying into a wormhole, which made it seem like he was on a planet for 600 years, while to the rest of crew it takes 6 hours to find him.
  • An episode of Sanctuary dealt with a village that was encased in a time bubble inside which time moved much faster. A character in his 30s who had been missing for a few weeks turned out to be trapped in the village and had aged about 40 years. Because the sun wasn't inside the bubble, days and nights each lasted years. The bubble is also expanding, and if encompasses the entire world, the Earth will tear itself apart. When they do close it, everyone who was born inside the bubble ceases to exist.
  • Stargate SG-1, the phrase "time dilation bubble" gets bandied about a lot. Probably best remembered in the fandom is "Unending": 50 years inside, about... 3 seconds outside. And they undid those 3 at the end, too.
  • An interesting take on this in Stargate Atlantis, where Sheppard gets stuck inside a time dilation field where time goes much faster than outside. When his team eventually understands what's going on, he has practically starved to death on the inside. This leads to a race against time for his team to get to him during his lifetime. They get him out in 6 months (by his reckoning)
    Sheppard: Never thought I'd see any of you again. Kind of even… missed you a little.
    Ronon: Yeah, well, it was only a couple of hours for us, so…
    Teyla: Ronon!
  • Star Trek:
    • In one episode of Star Trek: The Original Series, Kirk and Spock have to go back in time to prevent McCoy, who is out of his mind thanks to an accidental drug overdose, from changing history. They end up spending nearly a month in the 1930s waiting for the arrival of McCoy, who is there for at least a day or so himself. After completing their objective, they re-emerge in their own timeline to be told that they had "only left a moment ago".
    • Star Trek: Voyager:
      • One episode ("Blink of an Eye") has Voyager fall into the gravity well of an enormous M-Class planet, the gravity and spin of which causes centuries to pass down on the planet's surface in only a matter of hours on the ship. Curiously, it's also one of the rare examples that examines the physical hazards to transversing such time dilations; when a group of astronauts from the planet manage to hook up to Voyager, the stresses in the transition between their time bubble and that of regular space killed one of them and severely injured the other. A subplot involves the Doctor, a timeless, mobile computer program, going down to the planet for what's supposed to be a few seconds (a few days planet-time), only for the transporter to malfunction as they attempt to bring him back up, leaving him stranded for several hours ship-time. In planet-time, this is enough to make a life and family for himself. How in God's name a hologram fathered a son is quickly lampshaded and handwaved as "a long story".
      • In "Gravity", Tuvok and Tom Paris are trapped in a space sinkhole where time moves slower than on Voyager. After being stranded for two months, Tom is disappointed that his girlfriend B'Elanna doesn't miss him more because for her, only two days have passed.
      • Year of Hell uses time travel and narrative conventions to compress a year long epic war into two episodes that, in the end, never really happened anyway.
    • The Star Trek: Deep Space Nine episode "Hard Time" has Chief O'Brien being sentenced to a lengthy prison sentence. On this world however, serving your time consists only of having artificial memories of experiencing it inserted into your mind; thus, he serves what seems to him a decades long sentence and then awakes to find only an hour or so had passed. This is made much worse by artifical memories of a cell mate; by necessity, O'Brien had befriended the false man.
    • In "Playing God," a small proto-universe is created inside the station. The crew quickly figure a way to destroy it only for Dax to find evidence life exists inside it. Kira is dubious there could be intelligent life after only a few hours of its creation. Bashir points out they have no idea how time passes in this proto-universe and thus, billions of years could have gone by already. The idea of slaying countless innocent beings means the crew have to find a new way to handle this proto-universe before it destroys them.
    • Star Trek: The Next Generation: In "The Inner Light", Picard experiences an entire lifetime as the Kataan astronomer Kamin in just 25 minutes.
    • And he ended up with the same flute he liked to play in his dream state.
  • In Stitchers, Kristen has to enter the mind of a conspiracy nut only to find herself trapped in his mindscape. She spends a week putting together clues to finally figure out his message and be able to escape. She babbles about it to the crew, who are confused. Kristen meets Cameron, saying she knows she had him worried but she's happy he and the others elected to stay at her side for days on end. Staring, Cameron tells Kristen the entire stitch lasted three seconds.
  • Supernatural. Forty years can pass in hell with only a few months passing on Earth. Of course, hell is explicitly described to be deeply magical; time might just be an illusion.
    • It's explicitly stated that Dean experienced 40 years of Hell while only being dead for 4 months, and Sam experienced about 180 years for about 18 months. So, presumably, Hell is 5 Days Inside Hour Outside.
    • Averted with Purgatory however, where time passes at the same rate as on Earth.
  • That Mitchell and Webb Look spoofs Narnia, where a couple are thinking about buying a new cupboard and the salesman says it leads to Narnia. They ask to "try it out" and when they reappear they're king and queen of Narnia and five years have passed. He's still not sure about buying the cupboard, though.
  • Captain Jack Harkness and Captain John Hart of Torchwood spent five years in a time loop that was two weeks in the real world.
  • In the The Twilight Zone (1959) episode "100 Years over the Rim", a man leading a wagon train to 1880 California scouts ahead while his wife and son stay with the wagon and the other travellers. He goes over a nearby berm and sees an asphalt road in the 1960s. After being taken to a café, the owner's wife gives him some penicillin for his wounds. When he finds out his son will become a famous doctor, he runs back to the wagons, bring the medicine that will cure his son's fever. When he arrives, his wife wants to know why he came back after just a couple seconds.
  • Ultra Fight Orb: The titular Ultra needs to train himself to defeat the Ghost Sorcerer, Reibatos, but time is running out. So his two senior Ultra comrades, Ultraseven and Ultraman Zero, decide to put him through training in Zero's Shinning Emerium Field, a Golden Zone where time flows absolutely slowly. To outside observers maybe a few minutes have passed, but for the heroes, Ultraman Orb had endured ten years of training.

  • Dimension X: In "Beyond Infinity", the subatomic world that Eva and Allen are hidden in has a different sense of time than we do in our macroscopic world. The ten seconds that pass in our world represent billions of years for the subatomic world.

    Tabletop Games 
  • Changeling: The Lost makes Faerie's traditional Year Inside Hour Outside qualities seem even more chaotic by having it work both ways. An abducted human could spend two hours in Faerie, only to find that ten years have passed on Earth... or they could spend ten years in Faerie, only to find that two hours have passed on Earth.
    • Theres also the fact that it has no logic or reason to it that a human would understand, meaning that the relative time flow could be anything. And we really do mean anything. The ratio could be something like an hour outside for the colour blue inside.
    • A lesser example is the flow of time in the Astral Realms of Mage: The Awakening. Since they are a Dream Land, time is subjective to the one experiencing it. The amount of real time that passes largely depends on the degree to which the Astral traveller interacts with the Realm. For example, if one simply passes through a desert, it will seem to take hours, but in real time it will take as long as it takes to say "I pass through the desert". Its noted that in some of the deeper parts of the Astral, a person can take journeys which subjectively take years, or even centuries, even though only a few moments pass to outside observers. One can try to pass beyond the Earth's concept of the Solar System, which is very slow (no FTL in the Astral Realms, where there is a sense of scale) and will often be driven mad by the incredibly long isolation, while not succumbing to deprivation because it actually takes a few hours.
  • The same for Ars Magica; the faerie races live in isolated 'pockets' of spacetime known as regio; it's entirely possible to stumble into one by accident and not realize you're trapped until you stumble out again 250 years later.
    • One of the founders, Tytalus, was last seen heading into a faerie forest to challenge its lords to a competition. That was 400 years ago. A plot hook in Houses of Hermes has him emerge, claiming he'd had an enjoyable week with the faeries, only to realize how much everything has changed while he was gone. Meanwhile, the Order is freaking out because one of the founders has come back.
  • Many of the extraplanar realms in Dungeons & Dragons work this way.
    • In the Eberron setting, one group of Chessmasters use this to their advantage by spending weeks on their plane to plot their next move while only an hour or two passes on the Material Plane.
    • Module OA5 Mad Monkey vs. Dragon Claw. While the PCs stay on Monkey's island in another plane of existence, only an hour passes in the Prime Material Plane for each week the PCs spend on the island.
    • Taken to Inception-level extremes by B/X/C/M/I D&D module "M5: Talons of Night", in which the heroes must venture to a nested series of worlds where time passes 10 times faster than on the previous world. That's 10,000 times faster on the fourth and most accelerated for the worlds they visit. Needless to say, by the time the PCs arrive to retrieve the hostages they're seeking, all that's available for them to recover are some preserved tissue samples to clone the victims from.
    • Ravenloft:
      • Time flows faster in the Shadow Rift than outside. From the perspective of those who live within it, it's actually thousands of years older than the world it's a part of.
      • A minor darklord, Baron Evensong, is cursed to be trapped in his parlor every night. This wouldn't seem that bad of a curse, by darklords' standards, except that each night lasts 100 years from the perspective of everyone who's sealed inside the room.
    • The Genesis spell allows players to create small pocket dimensions. Creating one with this trait is a very common Munchkin tactic.
  • GURPS:
    • GURPS: Ultra-Tech has a number of time warping technologies such as the devastatingly effective Tau-Shields. Even at TL12 the technologies are the domain of superscience. In Spaceships the rules account for relatvity.
    • Also, both GURPS Time Travel (for Third Edition) and GURPS Infinite Worlds (for Fourth Edition) include rules for this trope, called a "Linearity Principle" — i.e., the ratio of time that passes in the past compared to "present time." In the Time Corps campaign setting, the usual ratio is 10 hours in the past = 1 hour in the present, but changes to history can collapse this ratio or even invert it.
  • Time flows differently in the Warhammer 40,000's warp, which is why the same Chaos Space Marines that fought during the Horus Heresy are still terrorizing the Imperium (up to 10,000 years later, depending on when the story in the Imperium's long history takes place). However time doesn't always flow slower in the Warp, sometimes it goes faster. Or backwards. Or sideways. Or purple. The laws of physics are little more than guidelines in the Warp.
  • Since every player is a time-traveller ("Spanner") in Continuum, this is a valid way to deal with problems. Stuck in a plummeting airplane with no idea what to do? Span out, take a few months of pilot lessons, span back in an instant after leaving and save the day. Players are encouraged to do this sparingly though, since the body only ages in one direction and big changes will get you noticed by Levellers.
  • Timemaster: On some Parallels, time flows differently than it does on Parallel T-0 (the Time Corps' "home parallel").

  • In the Broadway musical Brigadoon, the town appears in the real world once every 100 years. The time passes the same during the day. At night, the town moves forward to the next century.

  • Tamagotchi: One day in real life equates to one year within a Tamagotchi device. Averted with the Santaclautchi, which measures the days and is the only Tamagotchi to do so.

    Video Games 
  • Avatar Space in .hack//G.U. behaves this way - Avatar battles take a few minutes, but elapse over the course of only a few seconds to people without Avatars. The entirety of The World behaves this way at the beginning of Reminisce — and while it does, no one can log out.
  • Exaggerated in BIT.TRIP Runner2: The game begins by interrupting the end cutscene of RUNNER. After completing the hundred or so levels in the game, the ending returns CommanderVideo to that same cutscene one frame (1/60 of a second) later.
  • In Bullet Girls Phantasia, the Ranger Club discovers the hard way that a few minutes in earth equals several hours in Midgard, when they take what was supposed to be a quick trip for supplies and ammo.
  • Burnout Paradise is an interesting case. Thanks to an update to the game, players are able to change the time of day settings to whatever they want. You can choose from a 24 minute day cycle,note  a 48 minute day cycle,note  a 2 hour day cycle,note  a 24 hour cycle,note  match local time,note  or set the time to always be midday (12:00 PM), sunset (8:00 PM), midnight (12:00 AM), or sunrise (6:00 AM).
  • In The Coma 2: Vicious Sisters, Youngho asks how long it's been since Youngho fell into a coma and was taken to the hospital. Mina explains that it was three weeks ago, with Youngho revealing that what has been three short weeks for her has been years spent in The Coma for them.
  • These sorts of setups are quite possible in Duel Savior Destiny thanks to differing time flows between dimensions. The most extreme comes at the end when after Taiga beats up God several million times in a pocket dimension, upon return to Avatar only a few years have passed.
  • In The Elder Scrolls series, time tends to apply strangely and inconsistently to in the planes of Oblivion, the "infinite void" surrounding Mundus, the mortal plane. For example, prior to the events of Arena, Emperor Uriel Septim VII is imprisoned in Oblivion by his Evil Chancellor Court Mage Jagar Tharn, who then assumes Septim's throne. Septim is imprisoned for 10 years before being rescued by the Eternal Champion, however, when he emerges, he does not appear to have aged a day. Likewise, within the Soul Cairn, a plane of Oblivion created and ruled by the Ideal Masters (formerly mortal sorcerers who, through an unknown means, entered Oblivion as beings of pure energy and created the Soul Cairn to house the souls they traffic), time is said that the passage of time is "strange". In Skyrim's Dawnguard DLC, Valerica, a vampire, was able to live within the Soul Cairn for thousands of years without succumbing to the feral insanity that afflicts most vampires who go too long without feeding.
  • In Eternal Sonata, the events that happen are indicated to take place in the real world in a period of just over three hours during the dying throes of famous composer Frederic Francois Chopin, but the journey that takes place in his dreamworld extends for at least two weeks based on the information given, if not longer.
  • Final Fantasy IV aged Rydia from eight to twenty by claiming time moved extremely quickly in the Feymarch. Like the later Narnia books, when the party visits the place again later on, they're never inside long enough for it to make much of a difference.
    • This might seem to lead to Story and Gameplay Segregation if the player somehow spends more game-clock-hours in the Feymarch (actually pretty likely if they're searching for rare tails) than they did in the time-lapse from the point of Leviathan's attack (when Rydia leaves) until Rydia's return in the Underworld. However, one must remember that the time during which Rydia was absent was experienced by the player in regular time, whereas the time that the player spends in Feymarch happens in Feymarch time, meaning that the player's hours or days spent in Feymarch would have presumably only been minutes in outside time.
    • Touched further upon in Final Fantasy IV: The After Years where during Porom's chapter, Rydia takes the twins to the Feymarch, then tells them they can't go in because of the time difference. She goes in, and comes back out a second later, apologizing for taking so long. Palom and Porom give her a confused response.
  • The Shadowbringers story in Final Fantasy XIV explains that time on each shard flows differently compared to time's flow on the Source. The Crystal Exarch explains that an hour on the Source is a whole year on the First. When you complete the story and return to the Source to meet up with Tataru, she looks at you and is confused on how you came back so quickly after leaving for the First just a few minutes ago.
  • In Fire Emblem Fates, to protect their children, the main characters sent them into a Pocket Dimension, but it turns out that dimension runs on this trope and the kids come out from it aged up-in a few cases older than their parents.
  • The Formula: Timespeed rises far faster than your real second count. The Clock tab seems to think hours pass while you're playing for minutes, which soon become millions of hours.
  • In Gravity Rush, time flows differently in different areas; time in Boutoume passes a lot slower than in Hekseville. Raven (actually Sachya, Zaza's adopted sister) managed to get back to Hekseville somehow, then later returns after many years to help rescue the children stranded in Boutoume...only to realize that they haven't aged very much...
  • Half-Life 2 mentions off-hand the existence of several dimensions and how time and space works differently in each. Freeman didn't age between the events at Black Mesa and the events of Half-Life 2, probably because he was put in one of these dimensions by the G-Man, where Freeman decided to take a nap.
  • Hyperdimension Neptunia Victory concerns the protagonist falling into an alternate dimension where, after she manages to get in contact with her home dimension, it is revealed that time flows differently - from her perspective they failed to call back for a full three years, from theirs it just took them three days to find out anything about how to get her back. In the True Ending, however, both dimensions' Histoires manage to create a permanent portal between them, causing the time flow to stabilize between them.
    • In Megadimension Neptunia VII, "time being all wacky" is one of the first things Neptune complains about when she confirms she's fallen into the Zero Dimension. It never comes up again, as time between there and home ends up being one-to-one. There's actually a good reason for this, but it's not revealed until the game's end: the Zero Dimension is a creation of Kurome, who is isolated in the Heart Dimension, which is a prison dimension created by the Hyperdimension, meaning all three observe the same timescale.
  • The Legend of Zelda: Majora's Mask tasks you with saving the world from a falling moon that will make impact within 72 hours, which is roughly 54 minutes in real time. You'll be traveling back in time to the first day over and over in order to retry and be able to progress in other areas once you get the appropriate items. There's also a song in game you can play that will slow down the flow of time, allowing you to play for about an hour and a half before you have to go back in time to restart.
  • In Lost Odyssey, This is what causes the immortals, as a thousand years in the game world equals one year in their homeworld.
  • In the universe of Kingdom Hearts, it is said that time stands still for any world that has been consumed by darkness. This allows Sora to run around, swinging his giant key, without worrying about the residents of his home world, Destiny Islands, missing him.
    • A similar thing happens in the Realm of Darkness; characters state that "time does not exist" within it. One character (Aqua) is trapped within the Realm, and when she next meets someone from the Light, she's astonished to learn that ten years have passed outside. She doesn't appear to have aged at all.
    • In Kingdom Hearts 3D: Dream Drop Distance, Yen Sid mentions off-hand that Merlin and the Good Fairies created a space like this for Lea to learn to use a Keyblade.
  • In a Dummied Out line from King's Quest VII, Graham finds Rosella and Valanice after their adventure in the other world and asks them where they've been all morning, as they're late to lunch.
  • In The Messenger (2018), this is the method used in the shop located in the Tower of Time. From The Shopkeeper's perspective anytime The Ninja leaves the shop to continue his journey, time moves fast enough outside until The Ninja re-enters the shop. It also clues The Shopkeeper that something went wrong when The Ninja's new messenger didn't appear again moments after leaving the shop.
  • Pikmin 2: No matter how much time you spend underground, no time will pass at all in the daylight, due to the magnetic field below the surface of the earth.
  • In Quern - Undying Thoughts, this is how time works in Quern. One can spend centuries there and not age a day while hardly any time passes elsewhere.
  • While the time difference in Rakenzarn Tales isn't exact, it's certainly this trope. In Chapter 5, Kyuu returns to his world from Rakenzarn and discovers from Megumi that three days have passed while it felt like weeks to him. When he chooses to go back, after not much more than a few minutes in his world, three days also passed in Rakenzarn. And if you set things up to have Megumi come into Rakenzarn after you, however long it took her to find the book and get sucked in is long enough for the rest of Chapter 5 to about a a quarter of the way through Chapter 10 to have played out.
  • In The Secret World, time in the Hell Dimensions passes a lot quicker than in the real world, apparently due to the simple fact that the laws of physics have begun to decay in more or less the same fashion as the rest of Hell. As a result, Theodore Wicker has spent barely thirty years of Earth-time in Hell, but has been staging the revolution against Eblis for eons on end - hence how he's been able to become powerful enough to duke it out with the Devil.
  • In Sunless Skies, people who cross Her Enduring Majesty are thrown in the Midnight Cells, in which a minute lasts a day, and the prisoners are not let out until their hair is white and their bones are bent. There's also Hours, which are the material form of time and can be used to achieve this effect; the Workworlds in which they're refined have this effect within them, which makes the already awful industrialized nightmare even worse because for every small interval of time that passes outside them entire years can pass within, making them a living hell.
  • In Super Robot Wars Z2: Saisei-Hen, The location of the Getter Robo Armageddon Nuke Event is now on the Dark Continent. Gurren Lagann and Getter Robo participate because both series contain characters that need to age drastically, in a way that can't happen in a year like the others. ? The dimension quake will cause almost a decade to pass inside the Dark Continent until the seal reopens, while a year passes on the outside.
  • In Top Shop, each round represents an entire month, despite the actual rounds only taking a minute or so.
  • Occurs in the Ultima game series, so that with each game, the same main character visits a different time era.
  • Xenoblade Chronicles 2: The Land of Challenge, a pocket dimension created by the Nopon Archsage that transcends reality, is described by the Archsage as having one day passed in the Realm be 270 milliseconds on the planet Mira. Presumably, this logic also applies to both Alrest and the World of the Titans.

  • Akuma's Comics: Very early on, Tails and Amy end up in a void for what seems like a brief time. When they come back they've become an adult couple with a son of their own.
  • In episode 20 of Bonus Stage, in order to deal with growing a second mouth tied directly to his subconscious (don't ask), Joel enters the Room of Time where a day passes for every minute in the "real world". Phil comments on how impossible that is ("You can't possibly explain that with science or magic!") but leaves him in there for ten days anyway. By the time Phil gets back, Joel is a skeleton.
    • One day a minute means only about 3.95 years a day, so ten days is about 40 years. Were there food in that room?
  • This Casey and Andy strip has Jenn disappear into a portal and reappear a few seconds later, having apparently spent a few weeks on the other side.
  • A version occurs in The Dragon Doctors, where Kili takes the patient Greg into a dreamworld so he's not distracted as the doctors chip out a parasite from his temporarily petrified body. We see the seasons pass and they apparently spent enough time there with one another that they fell deeply in love.
    • Later Goro, Aki, and Amy are trapped in a time field where years pass in seconds. By the time they figure a way out Goro and Aki have had a daughter and raised her to adulthood.
  • In Dream Catcher Riza can go to Rokenthia for a few days and only have a couple of hours pass by on Earth.
  • In El Goonish Shive, Sarah's time stop simulation spell speeds up her perception while she's using it so she experiences more subjective time while in the simulation.
  • In Goblins Kore keeps the souls of those he kills sealed inside his body in a state of perpetual torment. Chief, having been temporarily released, is horrified to realize that what was years to him was only days for his companions.
  • Gunnerkrigg Court: In "Power Station", Zimmy, Gamma, and Annie's mental trip to Zimmy's Unhappy Place seems to happen at dream speed. Within the dream, enough time passed to wander through a city and get into a fight. But in the real world, it is short enough that only Kat — standing directly next to Annie — notices her comatose state.
  • Homestuck: After the events of [S] Cascade, John and Jade are stuck on a Prospitian battleship flying through Hussie's office across a yard-long space at the speed of light. Due to time dilation, their ship appears to be crossing one nanosecond per foot, but to John and Jade, each foot takes a year. (Which is the exact opposite of how relativistic time dilation actually works, but...)
  • Housepets!: King and Fox spend six months in Heaven "de-stressing" before Bahamut will see them. Fortunately time was suspended for their convenience and they return to the mortal world the day after they left. King is still a little annoyed that he spent so much time at a spa while his wife was fighting the avatars of a demigod.
  • In The KA Mics, Doc Unopoculum of SMOG spent ten years in a fast dimension one week.
  • Manifested, a webcomic about a normal guy who gets the power to travel into any fictional world he desires. He first goes into the Spider-Man world and after spending a year in there, he managed to return to his own world and the mysterious person who gave him the power said that only an hour and a half passed outside.
  • One arc of Wapsi Square has Shelly trapped in some sort of pocket dimension for thousands of years while almost no time passes back home. The experience leaves her nearly catatonic, and it takes time for her to start remembering her life and friends again.
  • xkcd (bottom left) shows us a practical use of this property: accelerated computation.

  • Sam, from the podcast The Bright Sessions, can go back in time for weeks or months, but when she reappears, only a few minutes have passed.
  • In the world of the Dream SMP, the Afterlife is revealed to function in this way in Season 3 — two days in the real world/Overworld is two months in the Afterlife, and three and a half months outside is equivalent to nine years inside.
  • SCP Foundation
    • SCP-119 ("Timecrowave"). SCP-119 is a microwave oven which can speed up the flow of time inside of it. Its power setting can be set in a range of 1-5. The time (in seconds) that the microwave is on is raised to the exponential power of the setting to determine the actual time that passes inside SCP-119. So if the power setting is 5 and SCP-119 runs for 30 seconds then (30 x 30 x 30 x 30 x 30) seconds (or 281.25 days) pass inside it. Anything (including creatures) inside SCP-119 experiences the full passage of time that occurs.
    • SCP-281 ("The Snooze Alarm"). When SCP-281 is activated, time speeds up in an area of 6 meters around it. While one millisecond passes in the outside world, 9 minutes pass inside the area.
    • SCP-415 ("The Harvested Man"). Occasionally SCP-415 is taken by unknown means into another dimension and returned after a few seconds. After being returned SCP-415 says he spent a considerable period of time in the other dimension, up to several years in some cases.
    • SCP-429 ("Clockwork Teleporter"). Testing reveals that when SCP-429 is activated without the instinctive understanding it grants, it will disappear and re-appear later within 1.76 kilometers of its previous location between 11 and 17 minutes later. However, approximately 8 months will have passed for anyone or anything attached to it during the teleportation.
    • SCP-455 ("Cargo Ship"), Experiment Log 455. During the second expedition into SCP-455 two weeks passed inside the ship while 10 seconds passed outside. During the third expedition ten hours passed inside the ship while a few minutes passed outside of it.
    • SCP-562 ("Revel Rousers"). After a person is lured through a door and enters the Revel, they appear several years later dead of old age. It's implied that time passes much faster in the area where the Revel is taking place.
    • SCP-728 ("The Forever Room").
      • During one test a subject inside SCP-728 experienced two hours of elapsed time while only five minutes passed outside.
      • In another test hundreds of years passed inside SCP-728 while only one hour passed outside of it.
      • In a third test several years passed inside the container while one hour occurred outside it.
    • SCP-826 ("Draws You into the Book"). A person can spend hours inside the book while only minutes pass outside.
    • SCP-860 ("Blue Key"). A 27 year old female spent 7 months inside the blue forest and emerged a very old woman, indicating that time passed faster than normal inside it.
    • SCP-1066 ("Instant Education"). During the 4-10 minutes a man subjected to SCP-1066 is gone he apparently spends four years getting a complete education in whatever he was thinking about at the time he signed SCP-1066.
    • SCP-1080 ("The Creche"). While the child is inside the chamber, between 3 and 5 days will pass on the outside while 7 or more years pass on the inside.
    • SCP-1130 ("A Handy Shortcut"). SCP-1130-2 is a series of interconnected halls, rooms and tunnels stretching for kilometers that is entered through the door SCP-1130-1. While people are traveling through SCP-1130-2 they report the trip lasting hours to weeks, while in the outside world only 11-23 seconds pass.
    • SCP-1230 ("A Hero is Born"). SCP-1230 is a book that produces tailor-made, fully immersive dream worlds for the reader when they next fall asleep. These worlds are adventure settings where the reader is the main character. The reader is usually never asleep for longer than they normally would, but one researcher who got so enamoured with his fantasy world that he didn't want to leave managed to keep it going for two hundred years (by the book's count) until he was forcibly booted out because the book simply couldn't keep it going any longer. This researcher couldn't handle a return to reality after two centuries of living out his greatest fantasies and so he immediately went into the bathroom and throttled himself with his belt. This guy was asleep for "only" fifteen hours.
    • SCP-1979 ("Relativistic Treadmill"). If SCP-1979 is not operated for at least 30 minutes per hour, a sphere will appear around SCP-1979. Time will pass more quickly inside the sphere than in the outside world. As the sphere expands, the multiplication faction increases exponentially. For example, at a 25 meter radius the factor is 10404 (1 second outside = 173 minutes inside). At 50 meters radius the factor is 108,250,000 (1 second outside = 206 years inside). And it just gets worse from there.
    • SCP-2400 ("Temporal Dilation Facility"). While the door to SCP-2400 is closed, time passes inside SCP-2400 at a rate 140 times normal.
    • SCP-2503 ("Estimated Distance: 9,216 Years"). Anyone trapped in the alternate universe of SCP-2503 must spend approximately 9,216 years walking inside of it (though without aging or needing to eat, drink, rest or sleep) to get out, while 80 hours pass on Earth.
    • SCP-2701 ("True Solitary"). A person stored in cell 667 experiences a period of incarceration 300-400 times as long as occurs in the real world. One prisoner was in the cell for 15 minutes and thought he had been inside for weeks. Someone inside it for two hours would experience a period of 25-33 days. Another person on the intake list isn't due for release until December of the year 3300-something.
    • ███-3955 ("Eight Notes"). The titular eight-note sequence were discovered when multiple music creating A.I.s were placed inside a "Time Box", which essentially works like this.
  • In episode 29 of the podcast Welcome to Night Vale, the town acquires, literally overnight, a subway system. When our narrator, Cecil, takes a ride, he reports that while only minutes passed for the listeners, to him the trip lasted for years.
  • In Worm Khonshu actually weaponizes this. He can create fields of speeded-up time. Anyone caught inside is trapped and experiences decades in the space of seconds, inevitably starving and dying. Those outside get to watch their friends' desperate struggles and inevitable demise on fast-forward.

  • Adventure Time:
    • In "Puhoy", this happens to Finn. He goes to a pillow world, grows up, gets married, and has children. After he dies, he wakes up again in his own world a few minutes later, and begins to tell Jake about a crazy dream he had. A phone call interrupts him, and Finn totally forgets even having a dream... if that's what it was in the first place.
    • In "The Hall of Egress", this seems to be mixed together with Mental Time Travel. Finn can only exit the titular hall with his eyes closed, and every time he opens them, he returns to the hall the moment before he closed them. Turns out he has to go through the hall twice, and accomplishes this by spending what's implied to be a long time, possibly years, wandering around with a blindfold on. When he finally breaks free for real, it turns out only a few minutes have passed.
  • American Dad!: This apparently happened to Klaus. After he uses a smoke bomb to disappear from sight, he reappears moments later with a crown and a sword (which he uses to cut his way out of a monster's stomach) and claims to have been gone for sixty years.
  • Avengers Assemble: In Season 4, the Avengers get scattered across space and time and Falcon ends up in a Bad Future. He spends roughly a decade there, but on returning to the present has only been gone for weeks.
  • Captain N: The Game Master: Sugggested when Captain N goes through a portal home. It turns out to be a fake, however.
  • Cyberchase: No time passes on Earth while the kids are in Cyberspace, and indeed several episodes have them spend days on problems in Cyberspace and come home when they originally left.
  • Darkwing Duck: Spoofed when Launchpad fiddles around with a time-travel device and suddenly vanishes in a puff of smoke, only to return two seconds later dressed like a Roman legionnaire. He is overjoyed to see everyone, as he just spent the last four years invading Gaul with the Roman army. The others just shrug it off and get on with the main story.
  • Doc McStuffins: This is exaggerated with the McStuffins Toy Hospital world. When Grandma McStuffins tells Doc that she'll probably be spending a lot of time there, Doc wonders about her parents worrying about where she is. As Grandma explains...
    Grandma McStuffins: No time passes while you're in here. They won't even notice you're gone.
  • Dungeons & Dragons (1983): Implied to be the case; after spending weeks or months in the Realm, they briefly make contact with a friend in their world and he tells them it's still the same day as when they left.
  • Final Space: In the episode "The Other Side", the crew comes into contact with a time shard that separates the ship in half while losing Gary, Ash, and Fox in the process. Roughly six decades pass by with Little Cato and the others desperate to survive, except it was only Little Cato who got pulled in having Gone Mad From The Isolation from the years of solitude. By the time Gary and the others pull the rescue, there was only a span of a few minutes.
  • In Invader Zim, Sizz-Lorr is angry at Zim for abandoning his duties/punishment on the Food Court Planet to join Operation Impending Doom II, leaving him critically understaffed for 20 years. Zim points out that he hasn't been gone that long, but it turns out there was a timewarp involved.
  • In Littlest Pet Shop: A World of Our Own, it's mentioned that the pets can stay in Paw-Tucket for as long as they want with no time passing in the human world.
  • Love, Death & Robots: In "Ice Age", time inside the fridge moves centuries for every few minutes on the outside. The miniature civilization that develops within it goes through the Middle Ages, the Industrial Revolution, a nuclear war, several increasingly advanced future eras and The Singularity over the course of a day.
  • Ninjago: With the reveal that Zane was in the Never-Realm for decades, it's implied that time moves at a slower rate in the Never-Realm. This was later averted, with Word of God confirming Zane was not only banished to a different realm, but to 60 years in the past as well.
  • In Over the Garden Wall, a Whole Episode Flashback shows how Wirt and Greg got to the Unknown, and when they escape in the final episode, no time has passed in our world, despite them having experienced at least several days and nights. Overlaps with Or Was It a Dream?
  • Penn Zero: Part-Time Hero indulges in this occasionally, with the time spent in the various dimensions being either the same as the characters' homeworld or weeks to months more. The episode "Ultrahyperball" has the characters spend years trying to accomplish their mission.
  • Popeye: In one cartoon, Popeye is in a space capsule helping test out one's endurance during sixty days in it. After losing his cool after hear Brutus (in a recording) gloat, Popeye sets off cans of aerosol spinach which launches the space capsule skywards at the speed of light. This causes him to go ahead in time sixty times normal while causing everything on Earth to go backwards. Brutus' time with Olive turns out to be all for naught.
  • ReBoot: The timescale has a second being equal to a day for the characters, who exist inside a computer system. It doesn't come up until season three, though, until Enzo becomes Matrix by spending so much time in the Games that he aged artificially. Apparently, when in the Games, they operate on our time scale, but age on theirs, so what feels like a (subjective) hour acts like an (actual) hour, or, about ten (subjective) years. Most games apparently last only a few (subjective) minutes, or Sprites have very long lifespans. Oh, and they also measure time in nanoseconds, microseconds and milliseconds.
    (Enzo is trying to become smarter by reading everything in the system files)
    Enzo: This is going to take millions and millions of nanoseconds. This might even take one whole second!
    • A second is a day, and a nanosecond appears to be an hour. Weird time.
    • It may be a little more subjective than that. The characters frequently use "in a nano" the same way we might use "in a minute". And during The Crimson Binome episode, Mr. Mitchell states that he hadn't had such fun in "minutes" as if referring to "years".
  • Regular Show: During the eight season, Benson enters a simulation room thinking its an escape pod and spends several decades in the span of five seconds before regretting his decision to leave the park behind.
  • Rick and Morty:
    • "Lawnmower Dog" includes the idea that going into someone's dream slows real time. When Morty is in Snuffle's dream for 6 real life hours, he tells Rick he's been there for over a year.
    • In "Mortynight Run", Rick and Morty go to an alien arcade where they play a virtual reality game called Roy. Morty seems to live an entire lifetime as Roy in a short period of time. In the next scene, Morty is still trying to make himself remember that it was just a game.
    • "The Ricks Must Be Crazy" takes this up to insane levels: the microverse Rick created works like this... and so does the miniverse that Zeep created in the microverse... and the teenyverse created by Kyle, a scientist in Zeep's miniverse. Rick and Morty spend months in the teenyverse (in the miniverse, in the microverse) and by the time they finally get back to the regular universe only hours have passed.
    • "Mort Dinner Rick Andre" bases an episode on this. By using a reality where time moves much faster to age some wine, Morty inadvertently becomes a mythical, terrifying monster to a civilization. Their fear spans centuries of development in their civilization, but less than an hour in Morty's reality.
  • Samurai Jack: The premise of the show is that the God of Evil Aku warped a samurai warrior with a magic sword into a Bad Future, and that samurai's quest is to find a way back to the past. In the Grand Finale, Jack does succeed in going back, and returns mere seconds after Aku warped him forward. For Jack, the journey was 50 years long. For Aku? "You're back already?" On the bright side, at least that means no one knew Jack was even gone.
  • In a throwaway gag on Space Ghost Coast to Coast, Space Ghost claims to have been a talk show host for thousands of years, but it doesn't seem so because on his home planet, it's still Tuesday.
  • The Star vs. the Forces of Evil episode "Running With Scissors" features Hekapoo's home dimension, in which a full year is equivalent to just 30 seconds on Earth. Marco spends 16 years there but has only been gone for 8 minutes. He re-emerges back to his home dimension and is sad to find his Future Badass body reverted back to being 14 years old. Hekapoo even lampshades it when Star finds them and explains how long Marco's been gone from Earth, much to Marco's shock.
    Star: 16 years? You've been gone from Earth for like, eight minutes.
    Marco: ...EIGHT MINUTES?!
    Hekapoo: Yeah, I forgot to tell you that time passes differently in this dimension. Not sorry.
  • Star Wars: The Clone Wars: In season 3's Mortis arc ("Overlords", "Altar of Mortis", "Ghosts of Mortis"), Anakin, Obi-Wan and Ahsoka are pulled to the titular Eldritch Location, and spend what seems to be at least two days there dealing with Mortis' residents. When they leave at the end of the third episode, they have only been gone for seconds at the most, as Captain Rex, who was talking to them via hologram at the beginning of "Overlords", tells them their ship dropped off the scopes of the Jedi Cruiser he's on for only a brief moment.
  • In Superbook (2011), Chris, Joy and Gizmo can spend periods as long as several weeks or months in an adventure, but when they return to the modern day, only a few minutes at most have passed. The episode "Gideon" has Superbook take them to witness the Israelites' battle against the Midianites and then return them home less than one second after the adventure began.
  • Voltron: Legendary Defender: In the sixth season, Keith and Krolia find themselves in a time pocket. They spend two years there before escaping, only to find that no time has passed in the real world.
    • The Voltron Palidins fought and defeated Lotor in a pocket dimension at the end of Season 6. They escape the dimension and on their way back to Earth, during Season 7, they find that however long they fought Lotor, three Earth years in their universe have passed.
