-  Although not required, it is *recommended* that implementations represent this type as an RFC3339 string when de/serializing to/from JSON, respecting the ``TimeUnit`` precision and time zone offset without loss of information. For example ``2025-01-01T00:00:00Z`` represents January 1st 2025 in UTC with second precision, and ``2025-01-01T00:00:00.000000001-07:00`` represents one nanosecond after January 1st 2025 in UTC-07.

-  The rationale behind this recommendation is that many programming languages provide support for parsing RFC3339 out of the box, facilitating consumption of timezone-aware JSON-encoded Arrow arrays without extra boilerplate just for integrating with Arrow.
