The TimeSync plugin (realtime) has been disabled and replaced with a plugin which allows both freezing time, and custom cycles. Currently the time cycle is:
- 1 minute Dawn
- 18 minutes Day
- 1 minute Dusk
- 8 minute Night
The /time command has also been disabled apart from admins.
There is a current issue with the sun, visually during the daytime, where you'll see it jump back occasionally. This is due to the longer daytime part of the cycle, and nothing can be done to fix it. It can only be fixed by clientside mods, and I don't think there are any at the minute.
