I think i've just worked something out...
The dates and times of each event on the calender has been adjusted to the timezone that you've set for the forum.
E.g. the Spring Break Dance Party event, is on 4th April 2008 PDT, which means its gonna be 5th April 2008 for me in Sydney.
Look at my calender:
When I click into it... it even converts the time for me...
So... that might be why Yosei missed the GM War event a little while ago?! (though i thought Yosei was in the same timezone... but this could be the answer....)
EDIT: actually.. not all events have that message in the 2nd picture... =/
