`isAdjustedToUTC` is exactly the opposite in parquet reader(https://github.com/apache/parquet-format/blob/master/LogicalTypes.md), resulting the time with `isAdjustedToUTC=true` has increased by eight hours(UTC8). The parquet with `isAdjustedToUTC=true` can be produced by spark-sql with the following configuration: ``` --conf spark.sql.session.timeZone=UTC --conf spark.sql.parquet.outputTimestampType=TIMESTAMP_MICROS ``` However, using the following configuration, there's no logical and convert type in parquet meta data, so the time read by doris will also increase by eight hours(UTC8). Users need to set their own UTC time zone in doris(https://doris.apache.org/docs/dev/advanced/time-zone/) ``` --conf spark.sql.session.timeZone=UTC --conf spark.sql.parquet.outputTimestampType=INT96 ```
