The problem with this is that people would have to
declare their time zones.
Seeing as the majority of players never visit the forums (which is the most convinient place to set a time zone), this would be difficult to do. Even in a signup phase, these things often get skipped for the default...how many times when signing up for a forum have to taken the second to change the default time zone forum setting...not many I'd wager.
a popup request could work...again, not the most effective means...and we cant force people because not everyone wants other people to know what time zone they are from.
It would be nice, but might be more hassle than it's worth.
But then, if Lack likes the idea later, who am I to argue
