I don't know how you're determining my timezone right now but it's not working correctly. When I plan a game it says the time in ADT when my timezone is AST. Use whatever you're using now to determine our timezone to set out default timezone, but allow us to change the timezone we are in and run our games in / want our times listed as - in our account settings. I'm sure I'm not the only one that isn't marked with the proper timezone.
while i am not marked in the wrong time zone it still agree that being able to set the time zone for everything is much needed as even i get confused sometimes when a game is based on other people not being in the right time zone.
