Thanks, again. However: "The jitter was usually between 1 and 3 ms" is
about a thousand times worse than I was hoping to achieve. Something to
keep an eye on, though.
You need a real hw PPS signal to get down to single-digit us jitter, the
only alternative is to have an expensive timing source which you can
query and which includes the hardware to timestamp each request.
From reading the ntpd driver sources I think the Palisade has such a mode?
