Hi, I would like to sync my CentOS 6.3 hardware clock time to my NTP server's time. Can I do that without reboot the hosts? If yes, it would be great if anyone of you can provide me steps to do that. I am newbie in CentOS. Thanks, Anand Singh

Otherwise it will take some time to adjust. -- Regards, Rajagopal

Compared to the ntpd way it will not listen on specific network port. Client way means using the /etc/rc.d/init.d/ntpdate service configured in /etc/ntp/step-tickers and /etc/sysconfig/ntpdate. Enabled it via $ chkconfig ntpdate on && service ntpdate start -- LF
