hi,

add the following in the cron of root.

00 * * * * /usr/sbin/ntpdate -b [server name]

GOOD LUCK!!

Now go get a baseball bat and hit your boss -- hourly. The far better solution is to properly setup your box as an NTP client and it will poll the time servers on as needed basis and will easily maintain time accurately to a few tens of milliseconds and probably much better than that. If you are unfamiliar with NTP then use SAM to set it up and start the service. There is an excellent starter document already on use box -- /usr/share/doc/NTP_Primer.txt. I suggest that you find a minimum of three NTP servers and xntpd itself will determine the "goodness" of them.

1,use
#crontab -e
to add following line

00 * * * * /usr/sbin/ntpdate -b server name
save and exit
2, check timezone of local server
#cat /etc/TIMEZONE. You can check on server if you have permission to access this file
HTH
ps: pls assign points.
