on the results of this change. The behavior is the same as the current Drill
behavior, except returning Local{Date|Time|DateTime} upon reading from the
vectors.
Notice the differences in Drill behavior in handling the date time data
from different data sources. We can separately decide how to make those
consistent. Fixing those differences are out of scope for this pull request.
