Well, just add my 2 cents to the discussion - you can check on the gw2stats when particular servers have their "prime income time" -chart called Income evolution.For example gw2stats.com/servers/view/4/You can see there, for the red server it starts after midnight on workdays (or sometimes even later - 1AM) and usually ends about 6-7 AM.As far as the clock hours are concerned - in EU, I believe starting from right to left - about from Poland to the Spain - the hours are the same. For Great Britain,Iceland it's one hour difference - in their favour (aka. Midnight in Madrit = 11PM in London).
