6 - 7 pm Central is cutting it way close for me - I get off work at 4 pm Pacific (which is 6 pm Central) and I don't think I can get out any earlier than that. If you could just push it back to start at 7 pm Central that would work for me. Any day of the week (preferably not today) would work too.

edit: WHOA, 4 PM Central? No freaking way, man. Not unless it's on a Friday or the weekend - I get off work at 11 am Pacific (1 pm Central).
