Hello All,
  I have a strange issue at the moment with regards ntp
working incorrectly on 35 of our Redhat WS Version 3 Linux machines. I
have
set them all up the same way so they use the IP of our Windows Cluster
machine I did this by adding the IP to the ntpservers file and the
tick-servers file. In addition edited the ntp.conf file to show the
cluster
IP as well.

What I seem to get is time differences on the machines within a day of
stopping and starting the ntpd service. For example I did this yesterday
and below shows all the machine times now ( 24 hours ) later, you will
notice there are 30 sec to a minute differences already and I bet with in
a week or a month they get even more out of sync. Has any body got any
ideas on what i can check or change to get this working correctly as
currently it is causing real issues when we run analysis jobs over night.

What does your ntp config look like? (grep -v ^\# /etc/ntp.conf)

Anything in the ntp log?

Kind regards,
