The reset time is pretty static on their end. It only shifts in america because of day light savings. Most of the year the reset is at exactly 12am pacific standard time for me. But after day light savings it's still at the same time, but it's now 1am to me.
The world is shut down for maitence at slightly different times but it's usually around 3:30-4am pacific standard time right now. Unless there is something wrong or a new patch it's usually up again within an hour or so.
