Owen O'Malley created ORC-37:
--------------------------------

             Summary: Represent the in memory timestamps using UTC rather than the local timezone.
                 Key: ORC-37
                 URL: https://issues.apache.org/jira/browse/ORC-37
             Project: Orc
          Issue Type: Improvement
          Components: C++
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley
             Fix For: 1.0.0


Change the representation of TimestampVectorBatch to be in UTC rather than local time.

The advantages are:
* More closely matches the SQL semantics of timestamp without timezone.
* Allows accurate representation of all values including the ones that occur
  during the local leap forward/back for daylight savings.
* One less timezone conversion.
