I can't really give exact time when I can or can't do it, really, because I really can do it anytime as long as it's not past midnight at my place or something. For reference, my time zone is exactly 12 hours after Central, so 2pm Central is 2 am for me. So something like, maybe before 12 PM central is alright, or after 6 pm central.

Except if it's Friday, then any time is fine.
