Type 1 or 2

The following information has been given:

	Myanmar (Burma)

Therefore TZ='Asia/Yangon' will be used.
Selected time is now:	Sun Mar  6 04:37:48 PM +0630 2022.
Universal Time is now:	Sun Mar  6 10:07:48 AM UTC 2022.
Is the above information OK?
1) Yes
2) No

After Select Yes

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