By the way, the code I am writing is not part of a NTP algorithm to
adjust a system clock for time. It is for a one-time frequency
calibration of an oscillator. I take a time snapshot at the beginning
and at the end of an approximately six hour period during which I am
counting cycles from the oscillator in question. I hope to achieve a
frequency accuracy of 5 PPM. Once that measurement is made, I store
it for subsequent use in my app. Unless the hardware changes, there
is no need to do the calibration again.

Robert,
I appreciate it's a one-time calibration, but if anyone needs a stable,
adjustable frequency source, they might look at the GPS disciplined device:
