Sync System Time

Sync System Time

This simple mod adds a new gamerule to make in game time reflect system (real) time. That means, for example, if it’s 8am for you, it will be 8am in your world too.

Usage

Only the server needs this mod installed to work, users do not need to have it installed on their clients. Installing it on the client will only add the new gamerules to the Game Rules menu when creating a new world, they appear in a new category and are fully localized.

Once the mod is installed, all you have to do is change syncSystemTime gamerule to true by using the /gamerule syncSystemTime true command. You can turn off this game rule at any time to return to normal time flow.

Note: The in game day counter does not progress while synchronizing.

Documentation
