Sand of Hours is an item from The Legend of Zelda: Phantom Hourglass. This mystical sand is a key component of the Phantom Hourglass: The more Sand of Hours Link obtains, the more time he has at his disposal when exploring the Temple of the Ocean King before the sand in the Phantom Hourglass runs out. By obtaining all the available sand, the hourglass has a maximum 25 minutes worth before it runs out. Interestingly, Oshus notes that the Sand of Hours is a physical form of life force, as well as being made of ground-up Force Gems.
