I double-click on the time in the bottom right to open the date and time panel. Then I click on the "Change date and time..." button (which has a shield) and I get the UAC dialog. I click "Continue", then am presented with an error that reads:
Unable to continue You do not have permission to perform this task. Please contact your computer administrator for help.
I will mention I have Comodo installed, but I have turned it off to test this out and I get the same results. All that I've found while googling were suggestions to turn UAC off, but I am interested in learning what the actual problem is.
Thanks in advance.
P.S. I am a member of the Administrators group, which has both "Change the system time" and "Change the time zone" rights.
