Yup, that's horrible, and something bad is clearly happening.
What's been syslogged by ntpd?
What does sysctl kern.clockrate say?
Have you let the box simply free-run without ntpd?
Alternatively, have you booted up such that ntpd free-runs,
with a bad drift value?
I'm quite satisfied that my userland + kernel, at least, is
quite happy ntp-wise.
