If we shoot for sometime over the weekend, it'd probably be for the best, as that's usually the most flexible days schedule-wise. Also, since the GMT+ people get on in the daytime, and the GMT- people get on at night, it kind of shortens the time gap a little bit. I'd probably shoot for something like Saturday, 11pm GMT-6. I could be totally wrong though, but that's just the way these things go.
PS: Right now over here it is 11:17am
