We haven't found a way to do this -- we're using openssl s_client to get the start date, but one of our own certificates for LastPass.eu also reissued without changing the date so we know it's a problem.
We wish we had all site's certificate fingerprints from before this started so we could utilize that data -- if anyone has it, an email to [email protected] would be greatly appreciated.
