So I am trying to achieve 12 ppm frequency calibration by developing a
temporary local time stamp that is disciplined by SNTP. I figure two
SNTP samples about 2 to 4 hours apart will give the required frequency
accuracy, assuming typical SNTP jitter.
I don't see why this should be better than (or even as good as) using
the system clock as disciplined by NTP.
It isn't, as long as the system is running a true NTPD implementation
instead of a bunch of sawtooth SNTP adjustments...
