"This is the clock song! We're setting all the clocks wrong!"
Though the clock says 7:30, it's really after ten
Looks like Lulu's been "repairing" it again.

Clock tampering is the art of changing the time on a clock so that you could make time be in your favor and trick others into believing it to be the true time. Some kid may do this in school when the teacher isn't looking, so they and their classmates can get out of school early, while an adult may make a clock go backward to forge his timecard and avoid getting in trouble with the boss for being late.

This trope is also used in mystery and thriller works, in which the murderer may alter the time on a clock to establish a false alibi about being somewhere else at the time of the murder.

  • Agatha Christie:
    • The Clocks: the murder victim is surrounded by six clocks, four of which have been stopped at 4:13. These clocks turn out to be Red Herrings. The unpublished book that the clocks imitated, however, directly implicated the killer as she was one of only a few people who had access to it.
    • Every time the old whodunnit trope where the victim's watch was stopped by the force of the murder, thereby giving the time of death, gets raised in a Christie book, someone will point out what an easy clue it is to fake.

While the class gets the test the next day, everyone has had a chance to study for it. Bobby would have gotten away with it completely if she hadn't tried a nearly identical trick as part of a practical joke just a few weeks later.

  • My Life Is Murder: In "Wild Life", following a "Eureka!"

Gundham sets all the clocks in the funhouse back 2 hours while everyone was sleeping, making everyone believe that they still had more time to sleep (they were close to starvation and dehydration, so they wouldn't try to exert themselves).

    Real Life 
  • Some schools have their clocks bolted shut or caged off to prevent such incidents from happening. Others have the clocks mechanically linked to each other so they will be in sync and can only be altered from a secure office.
  • This is a common trick among gamers to manipulate their gaming system's clock in order to trick a game into thinking a lot of time has passed, e.g. to solve a real-time Waiting Puzzle or to take constant advantage of events that only happen every x hours/days, although most games that have this as a major part of their gameplay have some kind of mechanism to prevent it, such as ignoring the system clock and using server time instead or checking that the current system time isn't in the past when compared to the latest save game timestamp.
    • Animal Crossing: This is basically the heart of the time-travelling cheat, where you manipulate the console's clock and calendar to get seasonal insects, fishes, and season-limited items sold at Nook's Cranny early. Some people also do it to manipulate the Stalk Market, the game's turnip gambling minigame. And of course some do it to exploit the Compound-Interest Time Travel Gambit since the game has a banking system that awards you a monthly interest based on the money you have in your account. Later games can detect this and will punish you by making your turnips become rotten and thus worthless if you attempt to do this and slip up (largely by detecting that the calendar and clock has regressed from the last save, a telltale sign that you attempted to travel back through time), and your villagers will allegedly guilt you by telling you that there is a rumor that you are a time traveller. A later update to Animal Crossing: New Horizons would severely nerf the bank interests so that the compound interest time travel gambit is not as profitable as in previous games.
    • Batman: Arkham City: By altering the PC's/Console's internal calendar to the dates circled on the Courthouse Basements Calendar would cause Calendar Man to recite unique dialogue linked to each holiday in question. There's an additional hidden one if you change the internal calendar to the 13th of December 2004 (the founding of Rocksteady Studios) which wasn't discovered until later. Adjusting the clock was a faster way to hear the unique dialogue as well as attaining the trophy linked to them. Depending on the player, it might even be the only way to get some of them, as some people might be obliged to spend some of the specified holidays at locations away from their PC/console for family reasons.
