I've just compared your server time against BBC time as shown in the text pages of both the analogue and digital (freeview) transmissions. Again you're more than 2 minutes ahead. (Interestingly, BBC analogue time seems to be ahead of digital time - not just the digital couple of seconds, but more than a minute.)
So - which clock is correct?

(Picture this - me sitting with my feet up in front of the telly, with a laptop on my lap, flicking from analogue to digital, comparing times and getting worried about a two to three minute discrepancy. Should I have posted in shifty-ben's "What makes you sad?" thread?
