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.

2) No

#? 1

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
