I use Blogger to post blog posts to my own site. Every post seems to appear dated about 5 minutes in the future.

I thought that maybe I had a "bad" server, with a wrongly set clock, but after several posts in a row all showed this I looked into it a bit more.

The proof would seem to be in Blogger's list of recently updated posts, which shows almost all posts as being in the future – so I conclude that it's a wider problem than simply one server with the wrong time.
