Are you sure that your /etc/ntp.conf ist correct?
# cat /etc/ntp.conf
server time.fu-berlin.de iburst maxpoll 9
Add other servers but don't use iburst, nor reduce the default
maxpoll. In your case try something like
server 0.de.pool.ntp.org
server 1.de.pool.ntp.org
server 2.de.pool.ntp.org
server 3.de.pool.ntp.org
Keep in mind that you will get better quality time by using multiple
servers at higher strata than you will by using just one stratum 1
server. Well managed stratum 4 servers really are good enough (and
often a better choice given availability).
Are there any messages from ntpd in /var/log/messages?
What's the output from "ntpq -p"?
# ntpq -p
No association ID's returned
#
That's not good. I think that adding more servers (as suggested
above) will help.
Also if you have other machines on your local network, you can use
them to peer with the one with the bad clock.
So add
peer some-local-net-machine
peer some-other-local-net-machine
to ntp.conf
I recall some discussion earlier on this list (I think) about these
problems with powerd and clocks. The solution involved some tuning
with sysctl or something similar. I'm sorry I can't be more specific.
You may also try to set things to restart ntpd on dial-up.
