Real Time Mod
Real Time Mod, published for NeoForge, syncs the in-game clock with the real-world time on the computer that runs it.
What it does
Game time follows the computer's clock, so an in-game day lines up with the local day rather than the fixed cycle that vanilla Minecraft uses. The mod adds a layer of realism to a world, and the time keeps running when no player is online. Players can set a per-player display format for the time, temperature and weather icons, and a hemisphere setting changes how seasons are read for the chosen location.
Season support is included, and the emissive temperature system shows a seven day forecast. Most features work with other mods without any added support, while content that needs support can be added through data-driven tags. Installation is on NeoForge only, for 1.21.1 and 1.21.8 among the 3 release versions, and the mod is published under All rights reserved, so it is not open source.
The mod is noticeably heavy on memory and CPU, and its tick updates are the main reason. Its author built it for lower grade computers as well, and the mod is made with MCreator, which limits how much of the code can be changed directly. Public links to an issue tracker and a wiki exist for reports and reference.
