* ''TimePaladinSakura'' seems to run on this: Sakura hears on the past her base is being attacked, and comes back to find it wrecked.
* In the ''InazumaEleven'' movie, Inazuma Eleven: Saikyō Gundan Ōga Shūrai, an organization from the future believes that the people of the future are too weak, and that the reason for this is due to soccer's attitude that soccer is fought for fun and that both 'enemy sides' are friendly with each other. Specifically they believe protagonist Endou to be the main cause, and they try and interfere with important events in his life that lead to him rising Raimon to success in the Football Frontier tournament (aka the events of the first season) by sending people into the past. Meanwhile, Endou's great-grandson Kanon also goes to the past to try and stop the bad guys. However, both parties, the bad guys and Kanon's team, treat the events as though they're happening in direct relation to them in the future. For example, no one sends anyone back to a point any further then we see the events of the past happening in occurrence to Endou's perspective.

* ''DonaldDuck'' time travel generally uses this rule, at least in the sense of characters returning X hours later. One especially convoluted example was [[http://coa.inducks.org/story.php?c=D+95022 a story]] where Donald and his nephews were sent back in time with the help of Gyro Gearloose's time-travelling bathtub to retrieve an atomic bomb accidentally sent back in time to the prehistoric era. During their mission they remain in contact with Gyro through a telephone, and both the past and present timelines run in parallel through the story, including a moment where a time paradox causes the planet Earth to [[DelayedRippleEffect start disappearing as history attempts to correct itself due to the effects of the bomb]], and then automatically un-corrects itself after Donald succeeds. Gyro's attempt to explain how the Earth was destroyed and un-destroyed when the bomb went off (even though it didn't) only manages to give Donald and the nephews a headache when they try to wrap their heads around it.
** Also by Disney, the stories where MickeyMouse and {{Goofy}} (and sometimes other people) travel on Prof. Zapotec's time machine. [[http://coa.inducks.org/story.php?c=I+TL+2458-5 Example]]: the duo complains about being called to see the Aztec's proto-soccer right before the finals of a championship, travel, and arrive hours later, where Zapotec has recorded the game and such.

* The ''Series/DoctorWho'' usage of San Dimas Time (see below) is intentionally averted and discussed in ''Forever Janette'' by [[RichsComixBlog Rich Morris]], which features the Fifth Doctor meeting the Master from the Seventh Doctor's timeline.

* In ''BillAndTedsExcellentAdventure'', Rufus tells the titular twosome that while they can go back in time to research their history project, time will advance normally in their hometown of [[TropeNamer San Dimas]]. They can intersect their past, but apparently their home time is always running. This is [[TimeyWimeyBall contradicted]] at the end of the second film, where the boys make what looks like a one-second time jump but come back after spending a year and a half learning to play guitar, marrying their girlfriends, having a medieval honeymoon, and fathering sons.

* Appears in ''The Prometheus Project'' by Steve White. The heroes are rushing to keep the villains from completing a time machine that will let them change the past, obliterating the present. They're too late, and the villains activate their machine. Fortunately, the heroes have a faster time machine, which they can use to catch the villains before they reach the past, even if they use the time machine later. Somehow, the past doesn't change as soon as the villains leave.

* The time travel in Creator/HPLovecraft's ''The Shadow Out of Time'' seems to work this way. When a member of the Great Race of Yith takes over a human body in the present, the said human's mind in turn goes back in time to the body of the creature that possessed him. The creature then spends several years in the person's body studying the history and culture of the era, and "meanwhile" the person spends equal amount of time in the creature's body, forced to write down all he knows about his own civilization. It's left very unclear if this is just for the sake of convenience, or because of some unknown law of time travel, however.
* In ''By His Bootstraps'' by Heinlein, Diktor apparently tried to invoke San Dimas Time on his predecessor self, but was rebuffed by, "How can we waste time when we have ''this''?" So he smoothed it over with fast talk and invocation of authority.

* L. E. Modesitt's Timegod series has this as an explicit rule: a timediver cannot superimpose himself or herself in space and time. So if one screws something up, he can't just go back a few minutes and try again.
* Whenever the protagonist of Creator/OctaviaButler's ''Kindred'' is dragged back in time to save Rufus, the time that passes in the present before her return is compressed but proportional to how long she spends in the past. When, for example, she spends a few minutes in the past, she disappears in the present for a mere second or two, but when she accidentally leaves her husband in the past, she spends three weeks in the present before going back and learning that her husband has been stranded for over five years.

* Averted in ''Time Travelers Never Die'' by Creator/JackMcDevitt. The protagonists realize early on that the clock is ''not'' always running in San Dimas, and use that fact to prepare for time trips or to bail themselves out of dicey situations.

** The big End of Act 5 Flash, [S] Cascade, involves no less than four different chronologies happening "simultaneously". For example, one of the major villains, [[spoiler:Jack Noir, destroys a universe from the outside shortly after that universe was created. At the "same time", the Scratch is initiated to reset said universe, while Jack's past self in the future of the same universe is trying to escape from its destruction. This universe then explodes at the "same time" as another universe, even though the second universe existed ''before'' the first one, and the first universe was destroyed 612 solar sweeps before the second universe itself explodes.]]

* ''Manga/InuYasha'': The time portal well can take people 500 years back and forward in time, but ''only'' that. If a day passes in the past, a day passes in the future. It's played more for laughs than anything, as Kagome's grandfather makes up ridiculous diseases that Kagome supposedly has as excuses for her missing school.

* {{Justified|Trope}} and used as a plot point in ''[[VideoGame/TheLegendOfZeldaOracleGames The Legend of Zelda: Oracle of Ages]]'', as the BigBad has stopped time at high noon around the construction site for the final dungeon. No matter how quickly you progress, [[YouCantThwartStageOne you can't stop the tower from being built.]]
** However, rather than appear completed instantaneously to your present self, the tower being built in the past progresses in increments as you progress through the plot.

* In ''VideoGame/GhostTrick'', every time Sissel does some time-travelling and returns to the present after averting someone's fate, it's always later than when he left (e.g., he left at 7:02 and returned at 7:21). [[FridgeLogic The use of this trope doesn't make sense upon analysis, though]], because Sissel isn't forced to travel X minutes/hours back and forth every time, but always to the same point in history: 4 minutes before a given person's death. He could wait ten hours to time travel and save their life and it wouldn't make a difference in the success of said mission.

* The time traveler's own body. While most works don't use such a long timeframe, the absolute maximum amount of time someone can spend time-traveling is the same as their remaining life span.

* Completely thrown out the window in the ''JusticeLeagueUnlimited'' episodes ''The Once and Future Thing.'' The timeline was described as [[TechnoBabble becoming fluid]], with different time periods merging together because of how much it was screwed up.
* An episode of BikerMiceFromMars had the BigBad (probably some kind of alien named after cheese, but who cares?) travelling into the past to demolish the city by digging giant holes where it would be built. Whenever he finished digging a hole, it would appear ''at the same time in the future'' in the middle of the city. Then again, what did you expect from a show about ''biker mice from Mars''?

* The Season 1 finale of ''Series/LegendsOfTomorrow'' has the [[BigBad Vandal Savage]] planning to set off three different {{Doomsday Device}}s in three different time periods simultaneously. Yes, simultaneously. And the heroes' plan to stop him is to split up into three teams, each heading to a different time period, so they can kill Savage in three different time periods, also simultaneously. And they're ''able'' to kill Savage, despite him normally being immortal, because being exposed to the radiation from all three {{Doomsday Device}}s simultaneously will render him mortal, even though he's never around more than one of the {{Doomsday Device}}s in any given time period. [[{{MST3K Mantra}} It's ... probably best not to think about it too hard.]]
