On one occasion, due to bad firmware or a configuration issue, I have seen GPS stratum 1 diverge from NTP. It was somewhat eye brow raising to the company. My NTP monitored servers were shown to be diverging their GPS/NTP, but after looking at twice or thrice, it was the other way around.We have two stratum-1 servers synced with GPS and a PTP feed from a provider that also provides PTP to market data systems, but we still have to monitor drift between system time and NIST time. Don't ask for the logic behind it, it's a regulation, not a technical requirement.
