I live in Asia.
There's not much chance of me joining a well organized ToD events and scenarious, but in the rare cases I see something I do not want to miss out, I have to start calculating at which time what's gonna start, having to change my GMT+9 hours time into first US eastern time, and changing that again into central, pacific, etc etc, according to situation.
My suggestion is, aside from the basic arena time, it would be great if there was also a time indicator, a clock, which synchronizes itself automatically with the time of what ever standard the many events and scenarios use.
For instance, people can quickly check what the arena time is from the tower, but there's no way of knowing when a certain event will start. They have to go outside the game, and starting futzing with the clock to see which time it is.
It would be really great if we could press a button to "check standard time" -> and it shows "8:12PM US/Central" or something like that.
