Arrow serializer sometimes shifts timestamp by one second

    XMLWordPrintableJSON

    Details

      Description

      This happens due to secondInMicros are calculated like

      final long secondInMicros = (secondInMillis - secondInMillis % MILLIS_PER_SECOND) * MICROS_PER_MILLIS;
      

      Instead this should be calculated like(by taking nanos from timestampColumnVector itself)

      final long nanos = timestampColumnVector.getNanos(j);
      final long secondInMicros = (secondInMillis - nanos / NS_PER_MILLIS) * MICROS_PER_MILLIS;
