[jira] [Created] (ORC-10) Fix timestamp moving between timezones (HIVE-8746 in C++)

Owen O'Malley created ORC-10:
--------------------------------

             Summary: Fix timestamp moving between timezones (HIVE-8746 in C++)
                 Key: ORC-10
                 URL: https://issues.apache.org/jira/browse/ORC-10
             Project: Orc
          Issue Type: Bug
          Components: C++, encoding
            Reporter: Owen O'Malley


ORC stores the difference from an epoch in the local timezone. That makes ORC mostly resilient when moving between timezones, but fails when moving between timezones with different daylight savings rules.

ORC currently stores the timezone information in the stripe footer, so that the reader can understand the times correctly.
