Google, Unable to login - Certificate Expired Error

Logging in to any of google's services will display a certificate expired error. This issue will occur if your computer clock is out of sync and displays an incorrect date/time.

Internet Explorer will display the certificate error and the post login process will stall. A temporary workaround to the problem is to enter the correct date/time through the windows date/time applet located in the systray. Attempt the login again after the date/time has been corrected.

Generally, a date/time error occurs due to a dead CMOS battery.

This issue affects all of google's services that require a google account- gmail, gtalk, google accounts, orkut etc.
