    Description

      With HIVE-20007, Parquet timestamps became timezone-agnostic. This means that timestamps written after the change are read exactly as they were written; but timestamps stored before this change are effectively converted from the writing HS2 server time zone to GMT time zone. This patch reinstates the original behavior: timestamps are converted to UTC before write and from UTC before read.
