I would submit that the proper use of a GPS receiver is for alignment of the start of the second to a more precise value than can be distributed across an asymmetric network like the Internet. The actual 'time label' for that second doesn't necessarily need to come from GPS at all. For security reasons, it's probably a good thing to make sure you validate the data received from GPS in any case.
