Time Weather Biome Control
by astrolddd
Time Weather Biome Control lets a player fake the time, weather, biome and moon phase shown on their own screen, without changing the world for anyone else.
What it does
A time slider from 0 to 24000 sets the sky time locally, and a weather mode switches between the vanilla clear, rain and thunder states. A fake biome selector changes the ambience and fog the client draws. Transitions between values are smoothed, so changes do not jump abruptly on screen.
The changes are visual and client-side only. Mob spawning, structures and other real world data stay as they are on the server, so the client view can differ from the actual world. Shader packs and custom sky resource packs can still choose to ignore vanilla time and weather, and when the pack reports values back to the mod, the pack's own settings take priority.
Time Weather Biome Control is published for Fabric only, across six game versions 1.21.1 – 26.1.2, with 1.0.0 for 26.1.2 as the latest file. It is open source under the Apache License 2.0 and is distributed with source code available.
Key features
Time slider
A slider from 0 to 24000 sets the sky time shown on the client without advancing the world clock.
Weather mode
The weather can be set to the vanilla clear, rain or thunder states for local display.
Fake biome selector
A selector changes the biome ambience and fog the client draws, while the underlying biome stays the same.
Smooth transitions
Changes to time and weather fade over several frames instead of switching instantly.
Moon values
The displayed moon phase can be adjusted along with the time, so night scenes match the chosen setting.

What the author says
The biome fake is intentionally visual/client-side. It does not change server logic, mob spawning, structures, or actual world data. Shader packs and custom sky packs can still choose to ignore vanilla world time, weather, biome, or moon values. In that case the pack's own settings win.
