The chat starts around 8-9pm my time. I live all the way on the West Coast and I usually log on around 9-9:30pm. Gothic is 3 hours ahead of me I believe? I think the last time we've discussed this he said he lived on the East Coast. Fly and Yoga are 2 hours ahead of me. If you can gauge something from that then coo :)
Also we can consult with this http://www.worldtimezone.com/ (it's not entirely live so you have to refresh to see the current time)
