FWIW, the LeoNTP unit will be far, far more accurate than anything you can do
involving Linux. With hardware timestamping on the Linux end, you can track
with a standard deviation under in the 20-30 ns range.
For comparison, my experience with Linux and attached serial is ~900ns standard
deviation, with common spikes in the multi microsecond range.
