minDateTime - works bad and different with minDate

[santaclaus21]

I'he got 2 fields "data_od_0" and "data_do_0". First is like "start date time" and second one like "end date time". So second one can't be lower than the first on. So I have to use both option "minDate" and "minDateTime" because the first one set only date and second one create limit for data_do_0. Additional, "minDate" [sets only date of field] and "minDateTime" [sets only limit, with no change in inputs]. After this manipulation I have to set manualy second filed $('#datado' + idy).val(dateStr), because of minDate set only date and minDateTime sets nothing on field - only limit... I'm a little confused. Even example on homepage isn't working fine (?!).

  $('input[id^="data_od"]').datetimepicker({
    //controlType: 'select',
    stepMinute: 10,
    minDate: null,
    onSelect: function(dateStr) {
    var idy = $(this).attr("id").substr(8);
    var min = $(this).datepicker('getDate') || new Date(); // Selected date or today if none
    $('#data_do_' + idy).datepicker('option', {minDate: min, minDateTime: min});
    $('#data_do_' + idy).val(dateStr); 
    }
  });

  $('input[id^="data_do"]').datetimepicker();

The problem is that:

$('#data_do_' + idy).datepicker('option', {minDate: min});

should working like:

$('#data_do_' + idy).datepicker('option', {minDate: min, minDateTime: min});
$('#data_do_' + idy).val(dateStr); 

And final, almost working for me code:

  $('input[id^="data_od"]').datetimepicker({
    stepMinute: 10,
    minDate: null,
    onSelect: function(dateStr) {
      var idy = $(this).attr("id").substr(8);
      var min = $(this).datepicker('getDate') || new Date(); // Selected date or today if none
      $('#data_do_' + idy).datepicker('option', {minDate: min, minDateTime: min});
      $('#data_do_' + idy).val(dateStr); 
    }
  });

  $('input[id^="data_do"]').datetimepicker({
    stepMinute: 10,
    minDate: null,
    onSelect: function(dateStr) {
      var idy = $(this).attr("id").substr(8);
      var max = $(this).datepicker('getDate');
      $('#data_od_' + idy).datepicker('option', {maxDate: max, maxDateTime: max});  
    }
  });
