Almost every GPS receiver also applies the UTC corrections to produce a 
UTC time. Infact, many of them can't externally produce any other time 
than UTC. Some has the ability to deliver GPS time or UTC time. Only a 
fraction of the receivers made only use GPS time, but then for some 
specific use.

So it is UTC and not GPS you should compare.
