I would prefer the night option to a time-zone based option. I don't really want to be messing around with time-zones. And the problem with following the sun is that a lot of games have advantages/disadvantages that are based on turn order. So if a particular group of people always want to play together, their turn order is always going to be the same just because of the sun. This seems a little unfair to me.
Also, many games have turn orders based on when a particular player passes, like Terra Mystica. Following the sun would only work for the first round of that game.
