Hourglass Sand
by Qiufeng
Hourglass Sand is a Fabric item that lets players control the flow of time, with four speed modes selected from a single item.
What it does
Holding the item and choosing a mode sets the tick rate of the world: stop freezes time, slow runs it at 0.5x, normal keeps 1x and fast doubles it to 2x. Each mode runs Minecraft's built-in tick command, so the effect follows the game's own timing rather than a separate system. The item can also reset the world with a single click, which suits testing redstone builds and timed events.
The mod is multiplayer ready and works for players on a server, with commands needed only when the item is used. Installation is a matter of dropping the jar into the mods folder, and no configuration is required to start. Hourglass Sand runs on client and server, so the server and every player need it, and it is released under the MIT License with its source code and issue tracker public. Its files target Fabric on 1.21.8, 1.21.9 and 1.21.10, with 1.0.0 for 1.21.10 as the latest.

Use cases
Testing redstone and machines
Freezing or slowing time lets a builder inspect a contraption step by step before running it at full speed.
Timed events on a server
Server owners can slow or stop time during an event so that players and their builds progress on a controlled schedule.
Who it’s for: Survival and creative players who want to pause or speed up the world, and server owners who run timed events or need to inspect automated builds.
