From the kolsole, how to change the time of the server? is it possible to add a cron job, that at a certain time the system time will be +1 hour?

OS : Redhat Enterprise 5.0

Thanks in advance.

You can use date command to change server time and date. Set time to 6:30:10PM
You must login as root and 6 (HH), 30 (MM), 10(SS), PM|AM

See Linux Set Date and Time From a Command Prompt

I'm sorry but I don't get your cron related question. Can you provide more info? Do you want to sync clock over the Internet using NTP?

hey man,
Thanks for your response. The issue is resolved. Here was my scenario,

Server 1 : have NTPD running, configured to take time from ntp.org
Server 2: also have NTPD running
Server 3: also have ntpd running


I did the following things.

Server1: Changed the time manually using the command u provided. Then put the server1's IP at the ntp.conf file. Restarted the ntpd
Server2: Put the Server1's IP in the ntp.conf . The restarted the ntpd
Server3: Put the Server1's IP in the ntp.conf and then restarted the ntpd.

So.. for now, all my servers are taking their time from the Server1. I will keep this as long as we have this +1 DST thing.

You can add this in your cron

crontab -e

then:

0,10,20,30,40,50 * * * * /usr/sbin/ntpdate <yourntpserver> >/dev/null 2>&1
