The first time I tried to go, I went at the wrong time. The times I saw are central time, and I'm EST, so I was an hour early.
CCG : Run Times!
This link has what I believe is the current, official schedule on it, down at the bottom of the first, long post. Read the stuff from the top - it'll help keep you from doing something stupid like jumping off the elevator, like I did. :-)
And then see the schedules at the bottom of that first post. This schedule is nice, since it has several time zones listed and you can be more sure you'll show up on time.
I hope this helps...
