It seems there is a record with a broken modified date `001-01-01T00:00:00Z` - https://github.com/pypa/advisory-database/blob/0676e94ac00584a7b0d66efcecd925a095be8d83/vulns/cipherbcrypt/PYSEC-2024-55.yaml#L4 We discovered it while importing it in [vulnerability-lookup](https://vulnerability.circl.lu/vuln/pysec-2024-55). and we were wondering why there are no `published` record too.
