The Dagger has the ability to reverse time, but for no longer than a minute. Its ability to manipulate time cannot be used in combat: When Dastan accidentally pressed the jewel pommel when attempting to fight Tamina, it immediately reversed time to before their fight, rather than aiding him in combat. According to Tamina, the Dagger "Is not much more than a dull knife" without the Sands of Time.
The Sands of Time are stored within the glass hilt of the weapon. How the Sands of Time are transferred into the weapon is never revealed, however, if need be, an amulet holding extra sand (likely created by the guardians of the Dagger) can be used to restore its depleted amount.
When its wielder manipulates time, the Sands of Time flow out and form an intricate pattern design on half of the wielder's arms and torso and create an impression of past moments as time reverses. The wielder is later transported back into their bodies the moment before the dagger is used.
The Dagger of Time was created when the Gods were convinced by a young girl to spare humanity. With the sandstorm trapped inside a sandglass, the Gods ensured that the only thing that could break the crystal was the Dagger of Time.
