Clocks are time-telling devices that display the current in-game position of the sun and the moon. Clocks only function properly in the Overworld.

Usage[edit | edit source]

The clock dial consists of two halves, a day side and a night side. The dial spins clockwise slowly to indicate the time of day, corresponding to the sun or moon's actual position in the sky. When the time of day changes suddenly, such as after sleeping or when /time is used, the clock dial spins rapidly to catch up. The player is able to sleep a few seconds after the clock shows exactly dusk.

The dial always shows the current in-game time when in the Overworld, regardless of where it appears. This includes a player's hand, an inventory slot, a crafting grid, an item frame, or even as a dropped item. For a clock to be mounted on a wall, an item frame is required.

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. Although clocks do not function in these dimensions, the actual daylight cycle does continue.

In Java Edition, a clock can be viewed under the item statistics page as long as one obtained a clock at some point.

Piglins[edit | edit source]

Piglins are attracted to clocks and run toward any clock on the ground, and inspect it for 6 to 8 seconds before putting it in their inventory.

Video[edit | edit source]

Note: This video doesn't state that clocks can be found in shipwrecks or ruined portals because the video was released in an earlier version.

History[edit | edit source]

Java Edition Alpha
v1.2.0			?				Added clocks.
							They have 230 visually distinct frames due to how the texture is generated – see the section below.
Java Edition
1.3.1			12w21a				Librarian villagers now sell clocks for 10-11 emeralds, making them renewable.
1.5			13w02a				Clocks now use the new animation feature included in texture packs. As a result, they are considerably less precise, having only 64 frames.
1.8			14w02a				Librarian villagers now sell clocks for 10-12 emeralds.
1.9			15w31a				Clocks are now broken up into individual textures, instead of having every individual frame on one vertical strip like with animated textures.
1.13			17w47a				Prior to The Flattening, this item's numeral ID was 347.
			18w14a				Clocks can now be found in shipwreck map rooms.
1.16			20w09a				Clocks can now be used to distract piglins.[1]
			20w16a				Clocks now generate in ruined portal chests.
			20w19a				Clocks no longer work in the recipe book.[2]
			20w22a				Clocks no longer work in the villager trading GUI.[3]
1.17			20w48a				The texture of clocks has been changed to match the new gold ingot texture from the texture update.
Pocket Edition Alpha
v0.2.0							Added clocks.
							Clocks currently have no function or legitimate method of obtaining them.
v0.8.0			build 1				Clocks are now functional and craftable. They have been added into the Creative inventory.
							The texture of clocks has been changed. They use a predefined texture file with 64 different frames.
Pocket Edition
1.0.4			alpha 1.0.4.0				Librarian villagers now sell clocks for 10-12 emeralds.
Bedrock Edition
1.4.0			beta 1.2.20.1				Clocks can now be found inside map room chests in shipwrecks.
1.11.0			beta 1.11.0.4				Trading has been changed, librarian villagers now have 1⁄3 chance to sell a clock for 4 emeralds as part of their trades.
1.16.0			beta 1.16.0.57				Clocks now generate in ruined portal chests.
1.17.0			beta 1.17.0.54				The texture of clocks has been changed to match the new gold ingot texture from the texture update.
Legacy Console Edition
Xbox 360	Xbox One	PS3	PS4	PS Vita	Wii U	Switch
TU1	CU1	1.00	1.00	1.00	Patch 1	1.0.1	Added clocks.
							Like in old versions of Java Edition, they use a dynamically generated texture with 230 visually distinct frames.
TU12							Alongside the addition of texture packs, clocks have been changed to use pre-rendered sprites. As a result, they are considerably less precise, having only 64 frames.
TU69		1.76	1.76	1.76	Patch 38		Clocks can now be found in shipwreck map rooms.
New Nintendo 3DS Edition
0.1.0							Added clocks.

Texture generation prior to Java Edition 13w02a and Xbox 360 Edition TU12[edit | edit source]

To generate its appearances, the clock combined 2 textures, one being the actual clock, and the other being the dial.

The logic solely for mixing the two (as there is additional logic for moving the dial in a wobbly fashion that isn't pertinent here) is as follows:

# Assume RGBA values are handled as 0.0 to 1.0 float values
def setup_clock_sprite (item: Image, dial: Image, dial_angle: float, output: Image):
	rx = sin(-dial_angle)
	ry = cos(-dial_angle)
	for y in range(item.height):
		for x in range(item.width):
			pix = item.get_pixel(x, y)
			if pix.r == pix.b and pix.g == 0 and pix.b > 0:
				u: float = -(x / (item.width  - 1) - 0.5)
				v: float =   y / (item.height - 1) - 0.5
				dial_pix = dial.get_pixel(
					int(((u * ry + v * rx + 0.5) * dial.width)) % dial.width,
					int(((v * ry - u * rx + 0.5) * dial.height)) % dial.height
				)
				dial_pix.rgb *= pix.r
				pix = dial_pix
			output.set_pixel(x, y, pix)

This results in the item and dial sprites being mixed by fuchsia areas of the clock sprite, as well as being shaded by them (contrary to the popular belief that they were mixed solely on the two shades found on the vanilla sprite). This allowed for the clock to be animated precisely, having 230 visually distinct frames, in an era where block and item sprites couldn't be animated individually without mods. The pre-rendered animated approach, used in 1.5 onward, is far less precise, with only 64 different frames.

Due to an oversight with how assets were loaded however, the item sprite for clocks couldn't be overridden by texture packs (as they are set to always load from the vanilla gui/items.png atlas, stored in minecraft.jar, rather than the one of the currently active texture pack.

Issues[edit | edit source]

Issues relating to "Clock" are maintained on the bug tracker. Issues should be reported and viewed there.

Trivia[edit | edit source]

• In Java Edition, the default resource pack for the clock contains 64 individual frames, each frame lasting about 18.75 seconds in real time (375 ticks) (1350 seconds (22 minutes, 30 seconds) in Minecraft time).
