DATime - Mod Time day/night
by Yoplay
DATime slows the day and night cycle of a Fabric world to roughly match real-world time, so one full in-game day lasts about 90 minutes.
What it does
Vanilla time progression is turned off with doDaylightCycle set to false. Instead of the default rate of 20 ticks per second, DATime moves the world's timeOfDay forward on its own, advancing it by 0.2222 ticks each server tick, or about 4.444 ticks per second. A full 24,000-tick cycle takes 5,400 seconds, or 90 minutes of real time, with the day running from tick 0 to 12,000 and the night from 12,000 to 24,000.
Only the world's time is changed. Entities, redstone and player actions keep their normal speed, and the server continues running 20 ticks per second, so the slower rhythm does not affect gameplay or server performance. The mod is server-side only, so players join without installing it. It is released under All rights reserved and is not open source. The latest Fabric file, 1.0.0, targets 1.20.1 and was published on 2025-04-11.
Key features
Slower day and night rhythm
The day and night cycle lasts 90 minutes of real time instead of the vanilla 20 minutes, giving a more gradual passage through the day.
Manual time advance
Time is advanced by a fixed fraction of each server tick, with vanilla daylight progression switched off by the server.
Gameplay speed unchanged
Only timeOfDay is modified, so mobs, redstone and player actions still run at normal speed.
Day and night split
Day covers ticks 0 to 12,000, about 45 minutes of real time, and night covers ticks 12,000 to 24,000, the same length.

How it compares
Custom Time Cycle is also server-side and open source, released under the GNU Lesser General Public License v3.0 only. It covers 1.20.1 – 26.3 and also has a NeoForge build, where DATime is Fabric only. realday is server-side, MIT licensed and published for 26.2 only, so it does not cover 1.20.1 the way DATime does.
