title: JQuery UI - Set minTime on timepicker based on other timepicker value
body: <p>I'm trying to set the <code>minTime</code> of my <strong>End Time</strong> <code>timepicker</code> based on what I've selected in the <strong>Start Time</strong> <code>timepicker</code>.</p>
  
  <p>I have this, based on something that works for the regular <code>datepicker</code>, but it's not working.</p>
  
  <pre><code>$('#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 
      });
  </code></pre>
