time

I'm asking this on behalf of a certain corporation:

http://www.microsoft.com/visualstudio/en-us/watch-it-live

Things to bear in mind:

It's 8:30 AM at different times depending on where you are in the world. For example, where I am, it is already 10 AM, whereas in Redmond it's still only 2 AM.

That's probably the main thing, I guess. Can any SO users recommend ways to improve the existing countdown page so that it works correctly for users in any timezone?

(Serious question - clearly this is a pit that is easy to fall into!)
