+If the data_type of a field is C<date>, C<datetime> or C<timestamp> (or
+a derivative of these datatypes, e.g. C<timestamp with timezone>), this
+module will automatically call the appropriate parse/format method for
+deflation/inflation as defined in the storage class. For instance, for
+a C<datetime> field the methods C<parse_datetime> and C<format_datetime>
+would be called on deflation/inflation. If the storage class does not
+provide a specialized inflator/deflator, C<[parse|format]_datetime> will
+be used as a fallback. See L<DateTime::Format> for more information on
+date formatting.
