From an offset from GMT it is easy enough with this:

to run up a listField with timezones and their countries as a sort of
ad-hoc lookup table.

The original poster does not want to have the offset, but the time zone
country/city and he already had a solution with apple script.
I provided a solution just with the shell function.

That seems a bit unnecessary as 'internet date' produces a format that includes
the GMT offset.
So when I write this in the messageBox: put the internet date
I get:
Wed, 14 Sep 2022 18:19:18 +0300
and, obviously, from the +0300 it is dead easy to work out
my system time zone.
Love, Richmond.

Does your app has preferences the user can enter? Why not allow him to enter
also the sudo password?
You could then use that to execute the following shell command:
put shell("echo <password> | sudo -S /usr/sbin/systemsetup -gettimezone")
replace <password> with the password in preferences. No need to use Applescript.

Just for the sake of completeness, there is a way to get the time zone with
AppleScript but it requires Administrator Privileges. The MacOS pops up a
request to allow the “do as AppleScript” script to access the systemsetup
function. That manual step will interfere with the flow of the program.
Create a field “Statements” with this AppleScript:
do shell script "/usr/sbin/systemsetup -gettimezone" with administrator
privileges
and put the following code in the script of a button:
on mouseUp
do field "Statements" as "AppleScript"
put the result into tResult
set the itemDelimiter to space
delete word 1 to 2 in tResult
delete the last char of tResult
put tResult into message box
end request
Tested in two time zones with these results:
America/Chicago
America/New_York
Bob
It's the, "America/Los_Angeles" bit I am trying to find a way to grok.
