One of six Infinity Gems that grant its user control over reality. According to the most commonly accepted origin story the six gems were once part of an all-powerful being who committed suicide out of loneliness. Its power survived and manifested as six gems.
For a long time, knowledge of the true nature of the Gems was unknown and the six were known collectively as "Soul Gems", with much of their powers unrealized by their users. The Gardener was the first known holder of the one that would eventually be identified as the Time Gem, using it to help create his gardens in otherwise desolate environments. He had set up such a garden on Earth's Moon when the Stranger, another Gem-holder attacked him in an effort to collect all six. In order to fend the Stranger off, the Gardener was forced to use his Gem offensively, an act which tainted the Gem in his eyes, making its capacity to destroy overshadow its capacity to create. The Gardener discarded the Gem on the once more barren Moon and departed.
The Gem was shortly thereafter picked up by Thanos on a quest to collect them all. He combined the Gem with four others and siphoned energies from the sixth to create a giant synthetic Gem with the intent of destroying the stars of the universe with its absolute power. The combined efforts of Warlock, Captain Marvel, and the Avengers thwarted Thanos' plan and destroyed the combined Gem.
For a time, the five combined Gems were thought to be destroyed, but a conclave of the Elders of the Universe eventually learned that they could not be truly destroyed in such a manner and that they were actually scattered across the universe. Having a plan to use the Gems to further their ambitions, the Elders set out to gather them together again. Of these, only the Mind Gem's circumstances were specified, having come into possession of the Kree. The Champion won one of the other Gems as the World Trophy of Grinx, the Collector collected one, and the Trader purchased the other two. It's unclear which of these was the Time Gem. The Elders eventually succeeded in gathering all six Gems together and connected them into a space platform aligned with a star system with six desolate planets the Gems could resonate with, setting up a trap for Galactus. Their apparatus would steal planetary energies from Galactus, channeling them into the planets, thus killing Galactus and subsequently Eternity due to the loss of balance that Galactus maintained. The universe would end and be reborn, with only the Elders surviving due to their earlier victory over Death and as such be true Elders of the new universe as Galactus had been in theirs. Though the Elders successfully trapped Galactus, they failed to handle interference from his heralds. While the Silver Surfer blocked the ray from the Gem apparatus, Nova detonated the star at the center of the system, creating a black hole that consumed the Gems and some of the Elders, saving Galactus.
The Elders joined with the In-Betweener in a further scheme to kill Galactus, retrieving the Gems from the black hole, but they were thwarted again by the Silver Surfer. Lord Chaos and Master Order became involved and redistributed the Gems among the In-Betweener and the Elders afterwards, with the one that would soon be revealed as the Time Gem being returned to the Gardener, who by now had grown beyond his concern for the Gems' perceived moral integrity.
The Time Gem eventually returned, suddenly transporting the Avengers into the future. 
The time gem allows the user total control over the past, present and future. Its most basic ability grants its user visions of possible futures. It allows time travel, control over the age of beings and also be used as a weapon by trapping enemies or entire worlds in unending loops of time. At its peak, when used with the other gems, it allows its user to exist at all points in time simultaneously.
2010s Marvel Animated Universe (Earth-12041)
In this universe, the Red Skull stole the Infinity Stones (as they are called, instead of "Infinity Gems") from his master Thanos and returned to Earth. He had his ship heavily damaged, which caused the Stones to be scattered all over the Earth. The Time Stone started fluctuating through time, but Iron Man was able to pin it down and seize it. However, the Stone got lodged in Iron Man's arc reactor. And each time the Stone pulsated, it caused Stark to de-age. Additionally, the arrival of said stone create temporal anomalies, like the appearance of dinosaurs, robots from the future, or Hydra battalions from WWII which wrecked havoc in Manhattan.
In the middle of the chaos, the Red Skull escaped his cell at the Avengers Tower, and tried to get the Time Stone, so he chased Tony Stark through the building, who had become a kid. Captain America fought the Skull to save Tony, and Stark managed to put on an adjusted Iron Man armor for his younger body. Tony attacked the Skull with a repulsor ray which blasted the villain out of the tower. Captain America was able to encourage the young Tony to focus and control the power of the Time Stone, ultimately succeeding in stopping the timeslips, sending everyone who was time-displaced to their respective eras, and reverting Stark back to his normal age.
The Stone was contained with the other three that had been retrieved by the Avengers, under special care by Tony Stark. However, the Black Widow noticed that Tony was slowly being corrupted by the Stones. She snuck into the vault and stole them, with the intention to send them to Asgard for safekeeping. Their plan failed, and they resorted to Doctor Strange so he could bury them between realities. However, Dormammu appeared shortly after to take the gems. Black Widow was forcced to wield the Stones in order to vanish him back to his dimension. After initially falling into the Stones' influence, Natasha was capable of resisting their control and reject them. However, as soon as she stripped of the Stones, Thanos returned, and assembled the Infinity Gauntlet with the Power Stone that was already in his possession.
Using the Gauntlet, Thanos created a citadel near Earth's orbit, and started modifying Earth's climate, causing anomalies around the globe. In order to defeat him, the Avengers got Thanos to fight them with each individual Stone. He first aged the Avengers until they died with the Time Stone, but Thor forced him to reverse time after causing the Titan's energy beam to backfire, aging him.
After getting the readings of each individual Stone, Iron Man activated Arsenal, who seized the Infinity Gauntlet from Thanos. When the Avengers returned to Earth, it was revealed a backdoor left in the robot's programming allowed Ultron to possess him. Arsenal was re-shaped into Ultron, and the evil A.I. revealed itself. The five Stones were drained of their power by Ultron.
Marvel Cinematic Universe (Earth-199999)In this universe, the Time Stone was held inside the Eye of Agamotto, a locket in possession of the Masters of the Mystic Arts. By using its powers to control the flow of time, Stephen Strange made time go backwards and prevent the destruction of Hong Kong, and later imposed a time loop upon the Dark Dimension to blackmail Dormammu into leaving Earth alone.
