Normally all players on the server would have to sleep at the same time in order to switch to daytime. This data pack allows you to switch to daytime if only one player sleeps in a bed.
How to install:
extract the downloaded file and paste the "Multiplayer sleep" folder into .minecraft > saves > your_save > datapacks
if your game is already running, you will need to run /reload in order for the game to register the data pack.
