> [WIP]
> 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.
