## Description

tzdata: Python package providing IANA time zone data
====================================================

This is a Python package containing ``zic``-compiled binaries for the IANA time
zone database. It is intended to be a fallback for systems that do not have
system time zone data installed (or don't have it installed in a standard
location), as a part of `PEP 615 <https://www.python.org/dev/peps/pep-0615/>`_.

This repository generates a ``pip``-installable package, published on PyPI as
`tzdata <https://pypi.org/project/tzdata>`_.

For more information, see `the documentation <https://tzdata.python.org>`_.

## AI interpretation — verify before relying

Provides IANA time zone database binaries as a Python package fallback for systems without system-level time zone data, implementing PEP 615.

Verdict: Stable, widely-adopted timezone data provider (top 100 PyPI) with zero vulnerabilities, no dependencies, and permissive licensing. Install friction is minimal and maintenance is active. Safe choice for systems needing reliable IANA timezone support.
