Both `Timestamp` and `TimestampLTZ` field will be converted to string and then passed to velox's `FromElementSource` to convert to timestamp. Different from `Timestamp` field string, the `TimestampLTZ` field string will be end with a ‘utc’ timezone character, such as `2025-08-29T12:12:12Z`, and it will be converted to timestamp with timezone by using `TimestampConversion#fromTimestampWithTimezoneString` in vlelox, and the `Timestamp` field string will be converted to timestamp without timezone. And then `TimestampConversion#fromParsedTimestampWithTimeZone` will make different behavior to the different converted timestamps according to whether they have timezone and the timezone that in `session_timezone` config. @PHILO-HE -- This is an automated message from the Apache Git Service.
