There may be times where a new timezone is needed, where in my case, the timezone for a country was not available (Myanmar).
To create a new timezone, I did the following:
$ vim myanmar.zone
Added the line:
Zone Myanmar 6:30 - MST
Saved and exited.
$ sudo zic myanmar.zone -d /usr/share/zoneinfo/Asia
This then created the timezone for me.
$ sudo mv /etc/localtime /etc/localtime.old
$ sudo cp /usr/share/zoneinfo/Asia/Myanmar /etc/localtime
Once this was done, I checked using date:
Thu Jun 16 21:11:39 MST 2016
Which was just super.
