Jannover5000r d2a84a8435 Removed Fatalf
in order to prevent a huge amount of restarts i removed Fatalf and made it return normally

I also made GetTime load the timezone once and just return the correct value as well as default to utc

made the Auth function retry 3 times per account and send an error after that

put time.Sleep into the correct loop in main.go

initUpdate is in main now
