Hardware clock time setting with NTP

+1 vote
76 views

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?

Does anyone has the steps to do that?

Following are the steps

ntpdate 
service ntpd restart

Before doing ntpdate adjust the clock to within a minute of network time. Otherwise it will take some time to adjust. Hope it helps.

Try this using root privs:

/etc/init.d/ntpd stop
/usr/sbin/ntpdate 2.us.pool.ntp.org # (or any other local public ntp server)
/sbin/hwclock --systohc
/etc/init.d/ntpd start

I suggest to use the client way to sync your time. 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
