InsaneLib is a library mod providing shared classes for Insane’s mods and assorted utilities. Available for Forge and NeoForge on Minecraft 1.19.1–1.21.1, it can pause day and game time, plus weather, when nobody is online. Seasonal cycling also pauses if Serene Seasons is installed, and Time Control is supported.
Rent your own Minecraft server and install InsaneLib with one click from the panel to keep world time from advancing while everyone is away.
