Depiction in the series
Season twoIn The Return of Harmony Part 2, Discord shows Twilight Sparkle a flashback to The Return of Harmony Part 1.
In It's About Time, Twilight is visited by herself from one week in the future. This future Twilight—having a messy mane and a scar on her face and wearing a tattered black suit, head bandage, and eyepatch—tries to warn her past self about something related to "next Tuesday morning", but she vanishes before she can deliver her message.
Believing that her future self was trying to warn her about an upcoming catastrophic event, Twilight spends the next week trying to prevent it. Over the course of the week, Twilight slowly takes on her future self's appearance due to a series of accidents. Unable to stop the "disaster" from happening, Twilight decides to stop time using a scroll in the Canterlot Archives, but she fails to find the scroll before Tuesday morning.
When no disaster occurs, Twilight realizes that she has been worrying over nothing. Using a spell to briefly travel back in time, Twilight tries to warn her past self not to worry about a disaster that isn't going to happen. However, she is pulled back to the future before she can deliver her message, effectively ensuring that the events she was trying to prevent will occur.
Season fourIn Princess Twilight Sparkle - Part 1 and Princess Twilight Sparkle - Part 2, Twilight uses a potion given to her by Zecora to project her consciousness back in time and experience visions of the distant past. In her visions, Twilight witnesses the banishment of Nightmare Moon, Discord's first defeat, and Princess Celestia and Luna discovering the Elements of Harmony in the Tree of Harmony.
In For Whom the Sweetie Belle Toils, Princess Luna shows Sweetie Belle visions of the past, present, and future through her dreams. In Equestria Games, after embarrassing himself throughout the Games, Spike asks Twilight if she could "turn back time" so he can get a do-over on the opening ceremony.
In Slice of Life, when Derpy accidentally messes up the invitations for Cranky Doodle Donkey and Matilda's wedding, she expresses a desire to "go back in time and fix all this." The science and mathematics-obsessed Dr. Hooves hears this and says he had been working on a theory of "making time come forward."In What About Discord?, Twilight misses out on spending a bonding three-day weekend with her friends. Rarity and Pinkie Pie briefly suggest time travel in order to relive the weekend's events, but Twilight says, "Time travel is not something to be messed with."
In The Cutie Re-Mark - Part 1 and The Cutie Re-Mark - Part 2, Starlight Glimmer uses a modified version of Star Swirl the Bearded's time spell to travel back in time to when Rainbow Dash performed her first sonic rainboom. As a result of Starlight's actions in the past, Twilight and Spike experience several alternate futures in which one of the series' antagonists rules or destroys Equestria. Starlight also takes Twilight and Spike further back to show how her friendship with Sunburst ended.
In It Isn't the Mane Thing About You, Zecora tells Rarity that the only way to regain her mane immediately is to travel back in time, but Twilight and Starlight, both remembering the events of The Cutie Re-Mark, assure them that time travel is not ideal.
Depiction in film
In the pre-credits scene of My Little Pony Equestria Girls: Friendship Games, Twilight goes to Canterlot High School and relates the events of The Cutie Re-Mark to her human friends, saying she was caught in a "time travel loop".
On pages 64-65 of The Journal of the Two Sisters, Princess Celestia writes about Star Swirl the Bearded's time travel spell and that he "desperately wants to travel through space and time with no limitations." On page 91, Celestia writes, "Whenever Star Swirl travels in time, he is very careful not to tell [Celestia and Luna] anything about [their] future."
In the Hot Topic promotional video Hot Minute with Twilight Sparkle, one of Twilight's interview questions is "IF YOU COULD TIME TRAVEL". Twilight answers, "I would love to go back and see Princess Celestia and Luna growing up together as young fillies."
In My Little Pony: Friendship is Magic Issue #24, Discord arrives to his monthly hangout session with Fluttershy a week early as a result of flying too fast and going back in time. When Fluttershy goes on a nature observation hike with the Cutie Mark Crusaders, Discord livens up the outing by taking the ponies on a journey through time. They travel to the lost civilization of Anugypt, the distant future, and the prehistoric era.
On My Little Pony: Friendship is Magic Issue #31 page 14, Pinkie Pie mentions that Ponyville's clock tower "at one time was mysteriously stopped by two time travelers visiting Ponyville", which Twilight Sparkle states is historically untrue.
On My Little Pony: Friendship is Magic Issue #60 page 19, Rarity quotes herself as having said, "Darling, feathers? What year did you time travel from?"

WHEN would I want to go."
