So how it's going to work? Server will go down prior to *release date hour / day* and then they'll be up when it's launch time or launch time is when the servers will go down to update?
AM in the morning, so if it's 12 AM it's midnight 00-00h. You can google it as well.
All that am/pm, why not use the 24 hours system instead for the European times?
Should have included Perth city in Western Australia, since it's the biggest city on that side and the timezone difference between us and Sydney is like 3 hours. You did a city for the far left and far right of the USA, so I'd figure doing the same for a country just as big would be a good idea. :P
