The TCA configuration property "dbType" allows to store "date"
or "datetime" values directly in the database (instead of using
a timestamp value).
However, the timezone is not recognized correctly - besides that,
the serverTimeZone is applied which does not make much sense at
all, since it leaves out DST handling.
