It should be your local day. I will check it, I am not sure, it's more than a year ago when I wrote this code :-)

Ah that reiminds me.. couple things I wanted to bring up on tournament signup deadlines... One is I think this might, indeed, be Czech time (I have to set mine 6 hours ahead of my local time to get it right).

But.. the more annoying thing is, when you edit a tournament (say, to add something to the description), whenever you hit the edit page, the hour jumps ahead by an hour. Edit twice without adjusting it before submitting, you're ahead 2 hours; three hits, three hours; etc.
