- 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.
- 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.
- If you wish, backup the previous timezone configuration by copying it to a different location. Such as mv /etc/localtime /etc/localtime-old
- Create a symbolic link to the appropriate timezone from /etc/localtime. Example: ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
- If you have the utility rdate, update the current system time by executing . /usr/bin/rdate -s time-a.nist.gov
- Set the ZONE entry in the file /etc/sysconfig/clock file (e.g. “America/Los_Angeles”)
- Set the hardware clock by executing: /sbin/hwclock –systoh
