OK, I'm not sure if this is where I should be posting this, or if it has been said before. But I haven't found it...

If the release date is the 25th, what time zone is it in?
Only saying because I live in UK and I want to be there for the launch (I haven't done this before, too lazy or wasn't thinking and got the box set) and I don't want to get the time wrong and log on late. So it would be nice to know what time it opens for me.

Thanks.
