How to change time zone in Linux !

1. Log in as root, check which timezone your machine is currently using by executing `date`. You’ll see something like “Mon Feb 12 05:09:00 CST 2007″, CST in this case is the current timezone.

2. Change to the directory to /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 “Americas” directory.

3. If you wish, backup the previous timezone configuration by copying it to a different location. Such as `mv /etc/localtime /etc/localtime-old`.

4. Create a symbolic link from the appropiate timezone to /etc/localtime. Example: `ln -s /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime`.

5. If you have the utility rdate, update the current system time by executing `rdate -s` or `rdate -s`

6. Synchronize hardware clock with system clock by executing: ` /sbin/hwclock –systohc`
