You can also use openssl's built-in utility* to see that the certificate has expired:
openssl s_client -showcerts -connect contracts.comcast.com:443
*You may also need to specify the path to your certificates using something like: -CApath /etc/ssl/certs/
To get the exact expiration date, it appears you have to do:

openssl s_client -connect hostname:port > cert.pem
2) verify date:
openssl x509 -in cert.pem -noout -enddat
