Purpose: When used with Self Service, enables a non-admin user
to change time zone on his or her Mac.
• The script will offer to set the time zone automatically
if it detects the time zone is set manually.
• Otherwise, the script will first present a short list
of commonly used time zones.
• If selected, the script will present a full set choices
based on UNIX time zones.
The script creates a log file in the user's ~/Library/Logs folder.
Except where otherwise noted, this work is licensed under

"To script is admin.
To comment divine."
INSTRUCTIONS
1) Below, create a short list of common time zones. Include as many
as needed to make the script easier to use.
2) Numbers for each time zone in the short listmust be unique
and sequential beginning with "1".
3) Add this script to your Jamf Pro server.
4) Create an ongoing Self Service item with the script and
enabled for offline use.
