TimeControl

A BepInEx 5 plugin for Valheim simple mod that adjusts the length of the in-game day/night cycle with a single multiplier.

I wanted the ability to lengthen the day/night cycle in certain types of playthroughs and this does the trick. A normal full game day/night is 30 minutes real-time. I have the default setting to 4 which makes it 2 hours of real-time for each in-game day (adjust as you desire).

Note: Ensure you consider any other mod timing dependencies. For example, if you have a mod that unlocks a boss after 100 in-game days, it will still unlock after those 100 in-game days. BUT, you will spend 4 times longer of real-time playing to reach those 100 in-game days...so you may want to adjust accordingly.

Install TimeControl on the server and on every client.
