Github user omalley commented on the issue:

    https://github.com/apache/orc/pull/87
  
    Ok, I took a pass at this:
    
    https://github.com/omalley/orc/tree/orc-135
    
    Changes:
    * Block all use of PPD on timestamps from before ORC-135.
    * Block PPD on timestamp with numeric constraints
    * TimestampColumnStatistics.getMinimum and getMaximum return Timestamps in the local timezone.
    * Loading old TimestampColumnStatistics loads the min and max assuming local timezone.
    * Add utilities to SerializationUtils for conversion to and from utc.
    * Make BloomFilter.encoding an int so that we can detect future values.
    * Future BloomFilter encodings are not used.
    * Some more test cases
