When we read from Parquet, we convert to UTC. When creating arrow schema from Parquet schema we hard-coded UTC. I have a PR https://github.com/apache/datafusion-comet/pull/2734 to remove that hard coding and that is a partial fix. When native comet scan reads from JVM LocalTableScan it is not always UTC, so we have a mismatch there. -- This is an automated message from the Apache Git Service.
