The following information has been given:
Korea (South)
Therefore TZ='Asia/Seoul' will be used.
Local time is now: Fri Mar 25 17:54:33 KST 2016.
Universal Time is now: Fri Mar 25 08:54:33 UTC 2016.
Is the above information OK?

You can make this change permanent for yourself by appending the line
TZ='Asia/Seoul'; 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:
Asia/Seoul
