Every time I right click on the time I see that the properties button doesn't work any more. When I first installed Zorin OS Lite I was able to click on the properties button and change the time and date. But I can't any more. Is there a way to fix this?
Can you press alt+F2 and in the popup window that opens, run
Then right click the Panel Clock and test the Properties.
I have never heard of this particular issue. I wonder if your timezone is locked in somehow.
