If I read the conclusion from #43 it was to potentially store these as
separate columns for day_time. So if we really want to introduce these types I
think not merging values together would be the way to go. Also, at least from
the Arrow C++ perspective, we don't have great support for the interval types
(duration is the preferred type in C++ see discussion on
https://github.com/apache/arrow/pull/3644)
