Google black for Earth Hour

It's after 12 here in the UK and Google's doing something a little special... it's turned off the lights for Earth Hour.

Google's page on Earth Hour says;

On Saturday, March 29, 2008, Earth Hour invites people around the world to turn off their lights for one hour – from 8:00pm to 9:00pm in their local time zone. On this day, cities around the world, including Copenhagen, Chicago, Melbourne, Dubai, and Tel Aviv, will hold events to acknowledge their commitment to energy conservation.

So I'm not sure they've got their timing exactly right. It's after midnight. Not after 8:00pm.
