There *is* a valid reason for having a time zone for date-only values - it
is then possible to determine whether a date-time value falls within that
date-only value. For example, 2015-02-27T00:30 in an Australian time zone
is during 2015-02-26 for a European time zone; it is earlier than
2015-02-27 in a European time zone.
