It looks like CloudFlare are counting down until 2012-06-06 00:00:00 in your local time, while the WorldIPv6Launch site is counting down to 2012-06-06 00:00:00 UTC.

That's correct. We were using local time and the World IPv6 Launch Day is using UTC time. We're going to update the CloudFlare page to also use UTC.
