Logged in as root, check which timezone your machine is currently using by executing `date`. You'll see something like Mon 17 Jan 2005 12:15:08 PM PST, PST in this case is the current timezone.
3
Change to the directory /usr/share/zoneinfo here you will find a list of time zone regions.Choose the most appropriate region, if you live in Canada or the US this directory is the "America" directory.
4
If you wish, backup the previous timezone configuration by copying it to a different location. Such as
mv /etc/localtime /etc/localtime-old
5
Create a symbolic link to the appropriate timezone from /etc/localtime. Example:
ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
6
If you have the utility rdate, update the current system time by executing
/usr/bin/rdate -s time-a.nist.gov
7
Set the ZONE entry in the file /etc/sysconfig/clock file (e.g. "America/Los_Angeles")
8
Set the hardware clock by executing:
/sbin/hwclock --systohc
