             Summary: Store TIMESTAMP WITH LOCAL TIME ZONE in UTC instead of writer's time zone
                 Key: HIVE-21094
                 URL: https://issues.apache.org/jira/browse/HIVE-21094
             Project: Hive
          Issue Type: Improvement
          Components: Hive
            Reporter: Karen Coppage
            Assignee: Karen Coppage


TIMESTAMP WITH LOCAL TIME ZONE (aka TIMESTAMPTZ) is stored in writer's local time, and the writer's zone is stored with it. When reading, the timestamp in reader local time + reader zone is displayed. This is misleading for the user, since it looks like all the data was written in the reader's time zone.

TIMESTAMPTZ should be stored in UTC time and be displayed in reader local time (as it was before) but without the reader's time zone.
