Comment (by ken@…):
For the little it is worth, an update to this. After assuming the time was
again accurate, I happened to notice it was 5 minutes slow. The cause
appears to be frequent suspend to RAM. I tried various workarounds, e.g.
reset it daily with ntpd -gq, retry the other clocksource. Eventually I
noticed that after waking the box, it could have large offsets (several
thousand milliseconds), but it did eventually sync. My thoughts now are
that I had left it sleeping for several days and that caused the offset to
be too great to sync.
I've added a script into /usr/lib/pm-utils/sleep.d/48ntpd to stop ntpd
when going to sleep, and when waking to run ntpd -gq and then start it
normally. That seems to keep it within less than a second (checking with
/usr/sbin/ntpq -p). I'll add that to the wiki under ntpd.
