If you find yourself needing really precise time with good guarantees,
you're not just talking about buying one GPS unit -- you can easily go
down a rathole of finding multiple units with good holdover

And you have to trust one single source: the US military.
Having my network outside the US and having read NOTAMs (notice to airmen) while preparing a flight stating that due to 
military ops the GPS signal was screwed up in that area I would not rely on GPS as my single NTP source for my network.
