 *           The fase will be brew. Enable setting of enddate.
 *        3. startdate valid, enddate and start and endtime can be set.
 *           The enddate cannot be before the startdate and not after 4
 *           days from the start.
 *        4. startdate and enddate and times are set and valid. Block
 *           the startdate setting. But only after setting a lot of
 *           brewdata and acknowledge set the fase to primary.
