TickWarpSleep

Once enough players are asleep, the server runs time at ten times its normal speed until morning arrives. Time skipping is removed, so the night passes through ordinary ticks rather than an instant jump. The check for how many players must sleep follows the playersSleepingPercentage gamerule, so the threshold stays under the control of the server owner.

The mod runs only on a server, and it is written for Fabric. Players join without installing anything, since clients need no part of it. Fabric API is required, and the mod has to be installed next to it. Files are published for 1.21.8, 1.21.9 and 1.21.10, with the 1.0.0+1.21.10 build as the latest. The mod is released under the MIT License, and its source code and issue tracker are public.

Because the change affects the whole dimension, the sped-up time applies to every player's surroundings in the world, not only the sleepers. Server owners who want a gentler night can leave the mod out and keep the vanilla skip.
