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.

IMHO, it's because you do not have administrator or power users rights. By default, only administrators and power users can change the date, time, or time zone. I like you to check this from MS.

Thanks for the feedback. I should have specified that I am a member of Administrators which has both "Change the system time" and "Change the time zone" rights. I will have a look at the KB link. – alexsome Mar 21 '10 at 13:03
