> final long secondInMicros = (secondInMillis - secondInMillis %
> MILLIS_PER_SECOND) * MICROS_PER_MILLIS;
> {code}
> Instead this should be calculated like(by taking nanos from
> timestampColumnVector itself)
> {code}
> final long nanos = timestampColumnVector.getNanos(j);
> final long secondInMicros = (secondInMillis - nanos / NS_PER_MILLIS) *
