IE 8 security certificates- server down?

I'm trying to get into paypal but IE AND Firefox are telling me that the security certificate is invalid. Is the certificate server down or is there something wrong in my interent settings?

Is your date (including the year) and time correct? This was the problem on another computer; the date and time invalidated the certificate.

working in Firefox, so it must be something wrong on your end.

Nvm my clock was set to Sept 4, 2006 XD

I reset my CMOS today and forgot to change the time.
