LAMP How To – Open Source At Work

having the wrong date and time in the system can be disastrous as many applications will be using the system date and time. It is therefore very important to have the right date and time.

In linux,

yum install ntp
chkconfig ntp on
ntpdate pool.ntp.org
service ntpd start

You can add the ntpdate command to cron to automate the syncing process. Another easy way is to do it in the GUI, if you have it.
