* Remove reference to utcnow This cleans up some of the datetime handling in the self check. Note that this changes the format of the state file, since the datetime now uses ``.isoformat()`` instead of ``.strftime``. Reading an outdated state file will still work on Python 3.11+, but not on earlier versions. * Use aware datetime object in x509.CertificateBuilder
