* ''Fanfic/WormGrandOrder'': [[Literature/{{Worm}} Taylor Herbert]] gets StuffedIntoALocker by bullies, then is ubruptly transported to [[VideoGame/FateGrandOrder 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.

* Neverland from the Disney version of ''WesternAnimation/PeterPan''. 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.

* ''WesternAnimation/WonderPark'': The protagonist June Bailey [[spoiler:returns home after being away thirty minutes (noted by her father) despite being in Wonderland for almost a whole day.]]

* ''Film/{{Inception}}'': An hour-long dream spans five real life minutes. [[DreamWithinADream But a dream begun within that dream can last an entire day.]] [[MindScrew Start another inside that and it will last a year.]] [[AndIMustScream 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.

* ''Film/{{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.

** In the sequel, ''Film/TronLegacy'', 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 [[UnroboticReveal 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.
* ''Franchise/MarvelCinematicUniverse'':
** In ''Film/ThorRagnarok'', 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 ''Film/AvengersInfinityWar'', 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 ''Film/{{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.
* ''Film/FourteenOhEight'': Time is one of the many things that don't function normally in room 1408. [[spoiler:At one point Mike is lulled into thinking it was AllJustADream, 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.]]

* ''Webcomic/{{Housepets}}'': [[spoiler: 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.]]

** "[[Recap/BlackMirrorPlaytest Playtest]]" shows that in the end, [[spoiler:it's revealed the entire play test only took .04 seconds. Not even the whack-a-mole was real]].

* Another [[Literature/AlicesAdventuresInWonderland Wonderland]]-inspired example is ''{{Series/Alice|2009}}''. The heroine spent about a week in Wonderland but only an hour passed in the real world.
* ''Series/{{Arrowverse}}'': In the first ''Series/{{Supergirl|2015}}''/''[[Series/TheFlash2014 Flash]]'' [[Recap/Supergirl2015S1E18WorldsFinest 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 [[Recap/TheFlash2014S2E18VersusZoom 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 [[Recap/TheFlash2014S2E17FlashBack into the past]] and [[Recap/TheFlash2014S3E19TheOnceAndFutureFlash into the future]], with people wondering if he even left, as barely a second has passed.
* In ''Series/AshesToAshes2008'' Alex spends around three years in TheEighties 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 [[spoiler: stopping at 09:06 when she died]]. Interestingly the timeline in coma and out-of coma for [[Series/LifeOnMars2006 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 [[DyingDream connection]] between the real world and the "dream" world.
* In the ''Series/BlackMirror'' special "[[Recap/BlackMirrorWhiteChristmas 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. [[spoiler: 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, "[[Recap/BlackMirrorPlaytest Playtest]]", shows that in the end, [[spoiler:it's revealed the entire play test only took .04 seconds. Not even the whack-a-mole was real.]]

** This is the twist in the ''Series/BuffyTheVampireSlayer'' 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 LifeEnergy. 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.

** However, {{Averted}} with Pylea: Winifred Burkle was trapped there for five years, in both that world and on Earth.

** [[Recap/DoctorWhoS27E1Rose "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 [[Recap/DoctorWho50thASTheDayOfTheDoctor "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.

** [[Recap/DoctorWhoS27E4AliensOfLondon "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.
** [[Recap/DoctorWhoS28E4TheGirlInTheFireplace "The Girl in the Fireplace"]]: Upon arriving on an abandoned spaceship, the Doctor finds an 18th century French fireplace, which is actually a TimePortal. 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.

** Done ''cruelly'' [[ButtMonkey to Rory]] in [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]]. Basically, a possessed TARDIS traps Rory and Amy inside of itself, and at one point it begins [[MindScrew 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 [[TearJerker because he waited for Amy to show up]] [[BreakTheCutie and she never did]]. Then Amy loses him ''[[RuleOfThree again]]'' and finds Rory dead, a skeleton in [[RoomFullOfCrazy 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 [[spoiler: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]].
** [[Recap/DoctorWhoS32E10TheGirlWhoWaited "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 [[Recap/DoctorWhoS34E6TheCaretaker "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 [[Recap/DoctorWhoS37E4ArachnidsInTheUK "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 [[Recap/DoctorWhoS37E1TheWomanWhoFellToEarth "The Woman Who Fell to Earth"]].

* In ''Series/EmeraldCity'', Dorothy spends approximately 10 days roaming through Oz but in the episode [[Recap/EmeraldCityS1E10NoPlaceLikeHome "No Place Like Home"]] [[spoiler:when she's sent back to Kansas, she discovers that only ten minutes has passed]].
* ''Series/{{Eureka}}'' has a similar one. By trying to save Kim through MentalTimeTravel, Henry remembers four years that will never happen. Oddly enough, the four years that Henry remembers [[TimeyWimeyBall aren't the same]] history that Carter remembers when he [[MakeWrongWhatOnceWentRight went back to stop him]], since the Henry that travelled back was the one who originally lost her.

* On ''Series/{{Heroes}}'', [[spoiler: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.]]

* ''Webcomic/GunnerkriggCourt'': In [[Recap/GunnerkriggCourtChapter19PowerStation "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.

* ''WesternAnimation/StarWarsTheCloneWars'': In season 3's Mortis arc ([[Recap/StarWarsTheCloneWarsS3E15Overlords "Overlords"]], [[Recap/StarWarsTheCloneWarsS3E16AltarOfMortis "Altar of Mortis"]], [[Recap/StarWarsTheCloneWarsS3E17GhostsOfMortis "Ghosts of Mortis"]]), Anakin, Obi-Wan and Ahsoka are pulled to the titular EldritchLocation, and spend what seems to be at least two days there dealing with Mortis' [[PhysicalGod 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.

* ''VideoGame/Persona3'' has this come up when investigating the disappearance of a girl at school after a bully locked her in a closet overnight. By the time this is discovered, days have passed since the girl's disappearance. However, there is the fact that the school transforms into the tower of Tartarus during the Dark Hour. Therein lies a sliver of hope: Tartarus only exists during the Dark Hour, so if the student is trapped in Tartarus, it may only be a few hours that have passed for her, and thus she could still be alive (provided the Shadows haven't gotten to her first).

* In ''Fanfic/BreathOfTheWild'', 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 first major arc of ''ComicBook/TheAmazingSpiderMan2022'' deals with this: [[spoiler:Peter and Mary Jane are drawn into an alternate universe, where they are tormented by the Scribble Man. Aided by a man named Paul, Scribble Man is torn apart and Peter is returned to the main universe...a week earlier. Peter spends a month trying to rescue Mary Jane, wrecking his relationships in the process, only to find out that once he did, four years passed in that world and Mary Jane fell in love with Paul and adopted two young children]].

* In the world of the ''LetsPlay/DreamSMP'', 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.

* In the ''Franchise/{{Ghostbusters}}''/''WesternAnimation/DannyPhantom'' crossover "[[https://www.fanfiction.net/s/3376586/1/The-Ghost-Child-and-the-Ghostbusters 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.

* Physicist David Wiltshire estimated that due to the effects of general relativity, time passes about 38% faster in cosmological voids (large, empty pockets of space between galaxy clusters) than in the Milky Way.
[[/folder]]

* The ''[[AllThereInTheManual Colonial Marines Technical Manual]]'' for the ''{{Franchise/Alien}}'' universe indicates that starships undergo "time expansion" during FTLTravel – [[SleeperStarship hence the need for hibernation pods]].

* ''Webcomic/{{Homestuck}}'': After the events of [S] Cascade, [[spoiler: 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...).]]

Be careful that this doesn't go in reverse, though. If more time passed in the "real" world, you're looking at YearOutsideHourInside. If you slept while more time than you thought passed in the "real" world, you're looking at the RipVanWinkle. If the relative flow of time varies, it's NarniaTime. In hard science fiction, TimeDilation will generally be used instead, as it's a real principle of physics. In other words, TimeIsDangerous. (Examples of TimeDilation should go on that page, not this one.) In softer works, expect to see a time dilation field or other {{Technobabble}} explanations instead.

** 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.)

* ''Franchise/DoctorWhoExpandedUniverse'': In the comic story "The Dogs of Doom," a [[OurWerewolvesAreDifferent 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.

* In the Film/KickAss 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.

* The director's commentary for ''Film/{{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.)

** In ''Literature/TheNumberOfTheBeast'', 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...)

** The short story "[[Literature/SkeletonCrew 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.

* ''Literature/MythagoWood:'' The deeper into Ryhope Wood you go, the stronger the effect will be, and the wood is BiggerOnTheInside, 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."

* ''Literature/TempestANovel'' 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."

** This is the twist in the ''Series/BuffyTheVampireSlayer'' 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 LifeEnergy. 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.

** 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 ''[[YearOutsideHourInside invert it]]''.

* ''Webcomic/{{Homestuck}}'': After the events of [S] Cascade, [[spoiler: 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...)]]

** Played with in the manga version of the original ''VideoGame/{{Angelique}}'' 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.

* ''VideoGame/{{Angelique}}'':
