Security Certificate error on IE firefox and Chrome

Last night suddenly I cannot access any website using any of my browsers. The following are the errors from different browsers
"The Site's security certificate is not trusted"
"Secure Connection Failed"
"There is a problem with website's security certificate"

All I see is a Security Error on all browsers. After a through search on the internet I was able to fix this problem.

Fix : Problem with CMOS battery I guess. Check if your system clock has turned to 2002 or 2006 or some date back to 4 years. Fix that restart the system and you are done
