Guild Wars 2

Has there been any official communication regarding the defend Lions Arch event? I have heard that it will be a one time event at 12pm PST. I have also heard that it starts at 12pm PST but continues for the remainder of the day. I am curious because I, like the majority of US players, will be working or at school at that time.

If I understand correctly the events on Friday and Saturday continues throughout the day and the one on Sunday is a one time event.

Enjoy the event!
