Not that I can find or have noticed.

no other time source loaded, I don't even think I have another one installed.

Well, I did most of that. I even adjusted the /etc/init.d/ntpd script to stop
and wait for ntpdate to run because I was having to stop and start the
service so often to get the time right.
And NO I'm not going to put ntpdate in the crontab, that's just not right when
there's supposed to be a time sync utility that keeps time. (not in Daniel's
email above, but another offshoot of this thread).
There must have been an update to the ntpd package, because since I updated
the ntpd script file and last restarted the daemon, it looks like time is
staying in sync.
root at home1:~# ps -ef | grep ntp
ntp 26249 1 0 Oct21 ?
00:00:01 /usr/sbin/ntpd -p /var/run/ntpd.pid -u 114:114
IF I read the above right the daemon was last started on Oct 21st?
However, the date and time show correct.
Here's an excerpt of what I did to the /etc/init.d/ntp-server script:
log_begin_msg "Stopping NTP server..."
start-stop-daemon --stop --quiet --pidfile /var/run/ntpd.pid
log_begin_msg "Starting NTP server..."
start-stop-daemon --start --quiet --pidfile /var/run/ntpd.pid --exec /usr/sbin/ntpd -- -p /var/run/ntpd.pid -u
I forget what it had, basically just some load lines calling the "stop"
then "start" sectons with "sleep 2" in between. The interesting thing is
that this daemon runs as "ntp" could that have something to do with it?
