Clock

"Keep track of the scary time! A craftable watch lets you know when it's safe to emerge from the caves."

Clocks are items that display the current in-game time by displaying the sun and the moon's position relative to the horizon.

Trading
A single clock can be bought from a librarian villager for 10 to 12 emeralds as part of their tier 3 trades.

Natural Generation
A clock can be found inside a map room chest in a shipwreck.

Usage
The clock dial consists of two halves, a day side and a night side. The dial spins slowly to indicate the time of day, corresponding to the sun or moon's actual position in the sky. The player is able to sleep a few seconds after the clock shows exactly dusk.

The dial can be read from a clock in any of its representations: held in a player's hand, placed in any inventory or crafting grid, in an item frame, and even as a dropped item.

Because there is no day/night cycle in the Nether or the End, clocks do not work properly in these dimensions. Instead, the dial rotates rapidly and randomly, making them useless.

Trivia

 * In the Java Edition, a clock can be viewed under the item statistics page as long as one has made a clock at some point.
 * When the time of day changes suddenly, such as after sleeping or when the time command is used, the clock dial will spin rapidly to catch up.
 * After completing 100 day-and-night cycles in the Legacy Console Edition or Windows 10 Edition you get an achievement and, on the Xbox 360 Edition, you are awarded a miniature clock wristwatch for your Xbox Live avatar to wear.
