TMO usually started around noon EST, or bit later if Zagum slept in

There is also the matter of the Bees though. It didn't really matter with the prenerf assraping version, but it really sucks for us now that we are the only guild that doesn't get to do them. So if you are going to move to Sunday AM I'd hope you could leave them up at least some of the time.
