You can make this change permanent for yourself by appending the line
    TZ='America/Regina'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
America/Regina
mag-sit@mag-sit:~$ sudo cp /usr/share/zoneinfo/America/Regina /etc/localtime
[sudo] password for mag-sit:
mag-sit@mag-sit:~$ date
Fri Dec  :: CST
mag-sit@mag-sit:~$ date -R
Fri,  Dec  :: -
