AFAIK ntpd v4 only tries to adjust the clock if a reference time source has
been configured which is not the local clock, and where it can pull time
from, or if it detects a driftfile with some value in it.

Since you have no other ref time source configured, ntpd is unable to pull
the time from some upstream source.

On the other hand you have configured a drift file, and if ntpd finds some
drift value in that file it "thinks" it is a drift value it has determined
before, and applies the corresponding drift compensation to the system

Try to delete the drift file, and remove the "driftfile" entry from
ntp.conf. No "enable/disable pll" entry should be required.

I'm not sure whether this also applies to xntpd (v3).
