> We currently use INT96 to store Timestamp values in Parquet files which will be deprecated in [PARQUET-323|https://issues.apache.org/jira/browse/PARQUET-323].
> We need to add read and write support for INT64-based logical types (TIMESTAMP_MILLIS, TIMESTAMP_MICROS) to our Parquet scanner and writer.
