How do I get information about whether the certificate is revoked and if yes, when it happened?

Revocation status is checked by (a) obtaining CRL lists and checking if the certificate is listed there, and (b) sending an OCSP request to the server to check the same.

SecureBlackbox offers OCSP client component for sending OCSP requests and CRL management component for dealing with CRLs. Also if you use TElX509CertificateValidator class to validate certificates, this class checks revocation status automatically (unless you turn off such checks).
