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:

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

Code:
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:

Code:
bash-2.05b# find /usr/share/zoneinfo/
/usr/share/zoneinfo/
/usr/share/zoneinfo/Africa
/usr/share/zoneinfo/Africa/Abidjan
/usr/share/zoneinfo/Africa/Accra
/usr/share/zoneinfo/Africa/Addis_Ababa
/usr/share/zoneinfo/Africa/Algiers
/usr/share/zoneinfo/Africa/Asmera
/usr/share/zoneinfo/Africa/Bamako
/usr/share/zoneinfo/Africa/Bangui
/usr/share/zoneinfo/Africa/Banjul

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

Code:
bash-2.05b# find /usr/share/zoneinfo/ | grep -i pst
/usr/share/zoneinfo/SystemV/PST8PDT
/usr/share/zoneinfo/SystemV/PST8
/usr/share/zoneinfo/posix/SystemV/PST8PDT
/usr/share/zoneinfo/posix/SystemV/PST8
/usr/share/zoneinfo/posix/PST8PDT
/usr/share/zoneinfo/right/SystemV/PST8PDT
/usr/share/zoneinfo/right/SystemV/PST8
/usr/share/zoneinfo/right/PST8PDT
/usr/share/zoneinfo/PST8PDT

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