jQuery UI - Establecer MinTime en TimePicker basado en otro valor TimePicker

Question

Estoy tratando de establecer el minTime de mi Hora de finalizacióntimepicker basado en lo que he seleccionado en el Hora de iniciotimepicker.

tengo esto, basado en algo que funcione para regular datepicker, pero no funciona.

$('#confirmed_time_start').timepicker({ 
    timeFormat: 'hh:mm', 
    stepHour: 1, 
    stepMinute: 15, 
    hour: 8, 
    minute: 0, 
    hourMin: 8, 
    hourMax: 18, 
    onSelect: function(timeStr) { 

     var newTime = $(this).timepicker('getDate'); 
     if (newTime) { // Not null 
     newTime.setDate(newTime.getDate()); 
     } 
     $('#confirmed_time_end').timepicker('minTime', newTime) 
     } 

    }); 

$('#confirmed_time_end').timepicker({ 
    timeFormat: 'hh:mm', 
    stepHour: 1, 
    stepMinute: 15, 
    hour: 8, 
    minute: 0, 
    hourMin: 8, 
    hourMax: 18 
    }); 

El error que estoy recibiendo es:

objeto no admite esta propiedad o método

var time = new Date(); 
$('#from').timepicker({ 
    ampm: true, 
    hourMin: 9, 
    hourMax: 19, 
    timeFormat: 'hh:mm TT', 
    onClose: function(dateText, inst) { 
     var startDateTextBox = $('#to'); 
     if (startDateTextBox.val() != '') { 
      var testStartDate = new Date(startDateTextBox.val()); 
      var testEndDate = new Date(dateText); 
      if (testStartDate > testEndDate) 
       startDateTextBox.val(dateText); 
     } 
     else { 
      startDateTextBox.val(dateText); 
     } 
    }, 
    onSelect: function(dateText){ 
     var time = new Date($(this).datetimepicker('getDate').getTime()); 
     $('#to').timepicker('option', 'minDateTime',time); 
    } 
}); 
$('#to').timepicker({ 
    ampm: true, 
    hourMin: 10, 
    hourMax: 21, 
    timeFormat: 'hh:mm TT', 
    onClose: function(dateText, inst) { 
     var startDateTextBox = $('#from'); 
     if (startDateTextBox.val() != '') { 
      var testStartDate = new Date(startDateTextBox.val()); 
      var testEndDate = new Date(dateText); 
      if (testStartDate > testEndDate) 
       startDateTextBox.val(dateText); 
     } 
     else { 
      startDateTextBox.val(dateText); 
     } 
    }, 
    onSelect: function(dateText){ 
     var time = new Date($(this).datetimepicker('getDate').getTime()); 
     $('#from').timepicker('option', 'maxDateTime',time); 
    } 
});
