### Search before asking - [x] I searched the issues and found nothing similar. ### Motivation Reading a Paimon table containing a `TIME` column fails during schema deserialization: ```text Invalid: deserialize failed, possibly type incompatible: parse data type failed, error msg: Invalid: Unsupported type: TIME ``` The Parquet table was created with PyPaimon 2.0.0 using an Arrow `time32[ms]` column containing `00:00:00.123`, `23:59:59.999`, and `NULL`. PyPaimon successfully writes and reads these values, but reading through the Vane Paimon extension fails. Tested with paimon-cpp commit `366323740cc13b5e113d9465080624b28e3880e8`, bundled in extension commit `b0ac989`. ### Solution Support Paimon `TIME` schema parsing and the corresponding Arrow time representation in the read path. Add a Parquet round-trip test covering millisecond precision, boundary values, and `NULL`. The current [type parser](https://github.com/apache/paimon-cpp/blob/a42670e066bba60100317cc0aa5a854b2273bf98/src/paimon/common/types/data_type_json_parser.cpp) still has no `TIME` handling branch. ### Anything else? The failure was reproduced through Vane, not a standalone paimon-cpp executable. ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
