is it possible to add UTC as a timezone in sierra

In previous OS X versions I was able to type in UTC for the timezone and not have a geographical location in the time zone preferences setting dialog, just UTC.

Also was able to update / patch the timezone files via terminal to add / correct them.

Still looking to be able to do that in Sierra, but it does not seem to accept the UTC time zone assignment in the timezone dialog using the command:

sudo ln -sf /usr/share/zoneinfo/UTC_/etc/localtime

Does seem to have accepted it in the underlying BSD, using the command:

systemsettings -gettimezone though.

Inquiring mind thinks that it has something to do with UTC not being listed as an available timezone in the command:

systemsettings -listtimezones
