### What problem does this PR solve? Issue Number: close #67370 Problem Summary: When the session time_zone carries the ISO-8601 zero-offset token "Z", the BE Arrow Flight SQL batch schema tagged TIMESTAMPTZ columns as `timestamp[s, tz=Z]`. "Z" is not a valid IANA zone name nor a fixed "+HH:MM" offset, so clients such as PyArrow/zoneinfo reject it (ZoneInfoNotFoundError) even though the epoch values are correct. This change rewrites the non-portable label (empty or "Z") to the portable "UTC" name; valid IANA names pass through unchanged. This matches the FE FlightSqlSchemaHelper, which already emits "UTC" for TIMESTAMPTZ. ### Release note None ### Check List (For Author) - Test: Unit Test (DataTypeSerDeArrowTest) - Behavior changed: No - Does this need documentation: No -- This is an automated message from the Apache Git Service.
