As it says in the title : the mod works but as soon as the day length is set to greater than 200 minutes, time stops completely.

Tested on :
Minecraft version 1.19,2
Forge version 43.2.8
No other mods than timecontrol
gamerule doDaylightCycle set to false
gamerule doDaylightCycle_tc set to true

I tried setting ' sync_to_system_time_rate' to 10 to see if that helps but it did not.

Thanks for reporting! I will look into this.

Sorry this took so long, should be fixed with 3bbc813 version 1.1.3.1
