The radio 4 pips can be wrong as well - if you have, say R4FM in one Room and R4DAB in another, and stand in the middle, there's a gap of about 8-10 seconds.

From wikipedia:

Newer digital broadcasting methods have introduced even greater problems for the accuracy of use of the pips. On digital platforms such as DVB, DAB and the Internet, the pips - although generated accurately - are not received by the listener exactly on the hour. The encoding and decoding of the digital signal causes a delay, usually between 2 and 8 seconds. In the case of satellite broadcasting, the travel time of the signal to and from the satellite adds about another 0.25 seconds.
