ForeverWeather

ForeverWeather freezes your world's current weather and time state. If it is raining, it will always rain. If it is sunny, it will always shine. You can freeze and unfreeze a world, keeping it in its current state or choosing your own state to have it frozen in.

Configurable via commands or config, quick, easy and small.

Quite simply, what this plugin does it take the time (in ticks) and the weather state, saves it and sets those values to the world every 10 seconds. This means that the time and weather roughly stays the same. On server load the information is loaded from the configuration file and applied straight away. However this does mean commands to set the time and weather will simply be undone every 10 seconds. The best part is that this is fully multiworld functional so you can have a creative world in constant daylight and clear skies or a world draped in darkness and rain constantly.

Please note:
I made this plugin for myself and my server, I am sharing my work for the good of others. I will not be spending massive amounts of time on this plugin, just making sure it works for myself. There will be small bugs and errors but you will be able to work around them at the very least by editing the configuration and restarting the server.
