Changing the date and time works fine. I just can't change the time zone.
I have tried via the GUI (logged in as my main named user (who I think has admin permissions), as well as when logged in as "Administrator")
Then I tried the "tzutil" via command line. (The CMD was launched from the run box using CTRL-SHIFT-ENTER for admin mode.)Unable to continue
You do not have permission to perform this task.
Please contact your computer administrator for help
