I have been running xntpd for awhile now on some of my FreeBSD systems,
and it seems that xntpd has to perform a step adjustment of about
-0.14 sec approximately once an hour to stay in sync with a non-FreeBSD
remote time source.  This is an error of about 40ppm.  On the other hand,
other FreeBSD systems seem to stay in sync with a FreeBSD master with
a stability of less than 1ppm.  This would seem to indicate that there
are still errors in the kernel timekeeping in FreeBSD.  Are any currently
known?
