tzdata on non-FHS-compliant systems
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

On environments without standard filesystem layouts (for example,
non-FHS-compliant systems such as NixOS, minimal containers, or hermetic
build environments), Arrow may fail to locate the timezone database and
produce errors such as:

.. code-block:: text

ArrowInvalid: Cannot locate or parse timezone '<timezone>'
discover_tz_dir failed to find zoneinfo

Arrow expects tzdata to be available in standard system locations (
``/usr/share/zoneinfo`` on typical Linux distributions). If tzdata
is installed in a non-standard path, it may not be discovered automatically.

If you encounter this issue, ensure that a timezone database is installed
and accessible in a standard system location, or configure your environment
appropriately.
