What time/timezone is the forst wipe next Thursday? It's the first thursday of the month.

I'm asking this because normally I wipe in the night from wednesday to thursday, but I dont wanna wipe like twice on the same day.

Also I want to reinstall my entire server to increase performance so it might take longer

Facepunch is based out of the UK I believe, so generally that timezone. 

Facepunch isn't usually punctual enough to know an exact time an update will happen, however they usually happen between 2-4pm CST for me.
