I want to create GMT file in UBUNTU usr/share/zoneinfo/Etc. I need GMT-3.30 and there is no file with this offset. how can I create GMT file or EDIT one of the GMT file ?
Create a text file :
sudo nano z330.zone
copy this to the text file
Zone UTC330 3:30 - UTC330
Compile it :
sudo zic -d /usr/share/zoneinfo z330.zone
If you want to set your time zone to what you made :
sudo timedatectl set-timezone UTC330
Verify :
timedatectl
