I think the OP meant, "What time do the servers go live?" If I misunderstood that, please excuse me. As for what time, I don't know. Most seem to go live between 9am-12noon release day.
I hadn't thought about that. I think it's pretty safe to guess, based on everything we've seen from XI's history, that they'll base the time of the servers firing up on JST.
This is total speculation, but if they went with 9am Wednesday Sept22 JST for the startup time, that'd actually be 5pm TUESDAY, the 21st for Pacific time.
If the above turned out to be the case, it'd put a whole new incentive on an in-store midnight release
At least for some people.... like me
