Time Freeze (Empty Server)

Server-side NeoForge mod for 1.21.1 that pauses day/night and weather whenever the server has zero players online and automatically resumes the moment someone joins.

Features

Freeze time and weather while empty
Grace window (configurable) before freezing to avoid flapping during quick reconnects
Zero client requirements (works with vanilla or modded clients)
Lightweight, no mixins

Commands

/timefreeze status – shows current state, players online, and config

Configuration

A server config file is generated on first run: config/timefreeze-server.toml

Options:

freezeTime (bool) – lock sun/moon cycle while empty (default: true)
freezeWeather (bool) – lock rain/thunder state while empty (default: true)
emptyGraceSeconds (int) – wait N seconds after last player leaves before freezing (default: 10)

Compatibility

Mod loader: NeoForge (21.1.x)
Minecraft: 1.21.1
Java: 21
Pure server-side logic; clients do not need this mod installed.

FAQ

Q: Does this stop gamerule doDaylightCycle changes?
A: While the server is empty, the mod re-applies the saved time/weather every tick. Manual time/weather changes will snap back until a player joins.

Q: Any known conflicts?
A: Mods that forcibly advance time or weather each tick might fight with the lock when the server is empty.

I have personally tested this with Serene Seasons with no issues. I will continue to monitor this since I will be using this for my modpacks :).
