ntp issue.

[Andrew.Bridgeman at corusgroup.com]

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.
