### Describe the enhancement requested Some timezone-dependent PyArrow tests require a discoverable system timezone database (tzdata / zoneinfo). On environments without standard filesystem layouts (e.g. non-FHS compliant systems or minimal containers), these tests can fail with errors like: ``` ArrowInvalid: Cannot locate or parse timezone 'CET' discover_tz_dir failed to find zoneinfo ``` There have been several mitigations over time like older interim fixes for Windows itself (#36996), PR #45425, and recent Windows CI fixes such as commit https://github.com/apache/arrow/commit/ab2c0ad6b23d05d5f77fc8a34d5a1c4baaacb0a4. Windows-specific failures appear to be largely handled now, but the underlying requirement and expected behavior are not documented for contributors on other platforms (e.g. non-FHS systems and hermetic environments). Happy to follow up with a small documentation PR if this sounds reasonable. The goal would be to clarify that these failures are environment-related and expected in certain setups, rather than indicating a bug in Arrow itself. ### Component(s) Documentation -- This is an automated message from the Apache Git Service.
