Change desktop time and date

Followed innumerable guidance to change Zorin 16.3 Pro desktop time and date (or region... typed in "Warsaw", at installation... inadvertently "accepted" Warsaw, N.Y... intended Poland :rage:),
Found it was easier to simply re-install Zorin OS with the the hope that it will, this time, find WiFi drivers, and router.

Zorin menu > Settings > Date & Time > Time Zone

It'll pop up a map that you can click. If you get it wrong the first click, click again until you get it right.
