> Is this an issue for Datafiles written with Avro Data instead of Parquet? Yes. In Parquet, there's only one data type for timestamps (`TimestampType`), and whether its a local TS type or an instant type is specified by type attribute `isAdjustedToUTC `. In Avro, there are two type families, `timestamp-<unit>` for instants and `local-timestamp-<unit>` for local TS. However, Iceberg incorrectly uses first one for both types. It is a bit strange because, say, when Iceberg writes ORC files, it does use appropriate ORC types (`timestamp` and `timestamp with local time zone`, in that case). -- This is an automated message from the Apache Git Service.
