Today my blog would not accept my Information Card when I tried to log in.

I got this error: The SamlToken is not time valid. The current time '5/7/2007 1:57:23 PM' is outside the Effective '5/7/2007 2:02:27 PM' and Expiration '5/7/2007 3:02:27 PM' time of the token.

The system is checking the validity of the two systems that are working with the SAML token.

Make sure your sever has the right time and timezone set, otherwise users will not be able to authenticate.
