Well, the US actually has 6 (7) different time zones, ranging from -6 (East coast) to -11 (Hawaii) hours compared to our time.
I find it funny that Arizona and Hawaii are the only states without daylight saving time. At Hawaii I see why, but continental Arizona?
And by the times they are online I mean they've been frequently online at 1:00 AM to 2:30 AM
their time. When do they sleep?

(Well, I'm online 1:00 AM to 2:00 AM my time, too.
