If you would like to change the timezone on your VPS here is how you can do so through an SSH session.

The idea is to create a symlink with the target being the timezone file in /usr/share/zoneinfo and the source as /etc/localtime

Here is an example of how to set it for CST/CDT:

bash-2.05b# ln -f -s /usr/share/zoneinfo/CST6CDT /etc/localtime
To verify that it worked:

bash-2.05b# date
Fri Jan 20 12:45:55 CST 2006
You may need to restart services on your VPS in order for them to recognize the change in timezone.

To get a full list of timezones that are available, use the following command:

bash-2.05b# find /usr/share/zoneinfo/

The output will be very long, but you can use the grep command to limit your search:

bash-2.05b# find /usr/share/zoneinfo/ | grep -i pst

bash-2.05b# find /usr/share/zoneinfo/ | grep -i turkey
