Short wants to have a time frame so that the server is up for certain hours and off for another certain amount of time.
This means that it would be on from about 10:00PM CST and off at around 11:00 CST.
The admins (flap, chode, and peng) would make a time frame that would fit everyone, so there is a pole on that so you can chose what time zone you'd like to have it set for.
I'm in the MST so I would vote for that, but if you were in something else then you would vote for that one you're in, the reason why I only chose the US time zones is because most of the players live in the US, I've made a pole that votes for none of them and you will choose that and post a reply telling us what time zone you are in and I'll put it in the pole.
