When sending a GeneratedCertificate to Credentials, send the associated CertificateDateOverride (if there is one), or else None. This will be triggered after any save of a GeneratedCertificate, and after any save or deletion of a single CertificateDateOverride. Credentials will eventually store its own copy of this date override, or edit or remove exiting date overrides.
