I was trying to pause the time to set up the server, and I noticed it eventually became night even though I had set the gamerule to false, which normally stops time.

It's a very minor bug, but a bug nonetheless.

Gamerules are Case-sensitive, in this instance, it should be doDaylightCycle are you sure you had it correct?

actually you're right I may have gotten the casing wrong, it seems to be frozen now. Sorry for that!
