In prior job, I did work for a datacenter.  Datacenter had both GPS and 
NTP.  We monitored drift.  We saw drift.  At first, I was dumbfounded 
that our NTP pool could be drifting.  Then I traced it back.  Found out 
that there was a misconfiguration on the GPS Receiver side instead.

Lesson learned: run both, track both, use each to confirm the other.  
Set one as priority over the other.
