AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Validates RFC3339-formatted timestamp strings, returning True or False based on conformance to the standard.

Low friction installation with a single lightweight dependency (six). However, the package is abandoned—last release was 2021-05-12 and last commit 2022-12-26, with no maintenance activity for nearly two years.

MIT license permits free use, modification, and distribution with minimal restrictions, making it suitable for both open-source and commercial projects.

Usage

pip install rfc3339-validator

from rfc3339_validator import validate_rfc3339

result = validate_rfc3339('2001-10-23T15:32:12.9023368Z')
print(result)  # True

Verdict: A minimal, permissively licensed RFC3339 validator with no known vulnerabilities and low install friction. However, its abandoned status since 2021-05-12 means no bug fixes or security updates will be forthcoming; use only if the frozen functionality meets your needs and you can maintain it independently if required.

Needs verification

Whether the validator correctly handles all RFC3339 edge cases beyond the documented examples.
Whether Python 2.7 support remains relevant given its end-of-life status.
