Deleting a time zone
When you delete a time zone, the time zone object is removed from the system. You can no longer access the time zone object.
You can only delete time zones that you have authority to. In addition, you cannot delete the time zone that is currently in use on the system.
Note: You should not delete
the IBM-supplied time zones.
To delete a time zone, use the character-based interface.
Use the Delete Time Zone Description (DLTTIMZON) command or the Work with Time Zone Descriptions (WRKIMZON) command to delete a time zone description.
