#? 23(남한 선택)

The following information has been given:

	Korea (South)

Therefore TZ='Asia/Seoul' will be used.
Local time is now:	Fri Nov 10 14:44:06 KST 2017.
Universal Time is now:	Fri Nov 10 05:44:06 UTC 2017.
Is the above information OK?
1) Yes
2) No
#? 1(적용여부, 1을 눌러 YES선택)

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

설정 후 위 설명처럼 ‘.profile’에 아래 내용을 추가 합니다.

#.profile 보통 파일 위치
/home/ubuntu/.profile

#.profile 에 추가할 내용
TZ='Asia/Seoul'; export TZ
