That's kinda good that it doesn't change, and NTP is designed to handle
500PPM of drift.  That value was at least 2x the worst clock normally
seen.

So if you can look at the tickadj program and calc_tickadj, you might be
able to adjust the system clock to be moch more stable.  Ideally the
drift value should be the smallest possible positive number, and that's
what calc_tickadj tries to do.
