Github user omalley commented on the issue:

    *Sigh* This is caused by the fact that Java defined Timestamp badly and then Hive copied
those semantics into the ColumnVector.
    
    We really need to fix these semantics in ORCv2.
    
    I'll also comment that it would probably be nicer to our users if we weren't modifying
the data in the columnVector they passed into us, but clearly we are already doing that.
