Tz-naive timestamps have no timezone and should therefore be left as is IMO (applications on top of Arrow can choose to use the "naive means system time zone" behaviour, but I would say that Arrow itself should never deal with the system time zone)
   
   You've probably seen this, but this is what our docs say about timezone-naive data: http://arrow.apache.org/docs/cpp/api/datatype.html#_CPPv4N5arrow13TimestampTypeE
   
   (Side note: do our doc URLs have to be so ugly?)
   
   I agree with Joris that at this level, we should not do any localizing of timezone-naive data.
