After close to a week of calibration, I fudged then flipped off
noselect on my GPS+PPS refclock in the early minutes of the UTC day.
It looks to me (from my limited perspective of no other local
refclocks) that I've gone from single-digit milliseconds to double-
digit microseconds accuracy.
Looking at the last 800 loopstats lines for the refclock, representing
a bit more than 3 hours of 16s polls, the offsets in microseconds look
The jitter (us)
How does that look to more jaded PPS eyes?
The refclock is a Garmin GPS 18x LVC connected to a dual PII 400 via
serial with PPS wired to the carrier detect pin.
