OS took a shit last night and I SWEAR TO GOD it wasn't anything to do with the actual system itself it was this FUCKING EXTENSION for GNOME that caused it.  Locked up the system something fierce.  Reinstalled the OS and installed the same extension almost straight away (shortly after GNOME DO!!!!) and before I knew it, same exact shit. So fuck the world clock extension, both full & light.  I'll go as far to say the hell with Gnome Clocks too.  `date -u` for the mother fucking win.  What a waste of a night.  Not complaining too much, it was sort of nice to wipe the baby clean after our first go with 18.04. Cheers!
