• I made sure this command is not in the commands list
• I searched and didn't find this command in the listed issues
• I know this defaults command exists
• I know this command works on macOS current version
• I know this command is deprecated on macOS current version

When time zone support is turned on in Calendar (Calendar → Settings → Advanced → Turn on time zone support), this command clears all time zones from the time zone selector (other than the currently selected time zone).
