title: Datetimepicker not working with different formats
body: <p>Hi I was trying to make a filter for reservations where people would be able to filter in between what dates they want to register. I used datetime picker (<a href="http://xdsoft.net/jqplugins/datetimepicker/" rel="nofollow noreferrer">http://xdsoft.net/jqplugins/datetimepicker/</a>) but the form to pickers are not working(is not letting me to chose a date from). I am using d.m.Y format and that seems to be the problem as it is working with Y/d/m but we cannot use this format. Here is my code:</p>
  
  <pre><code>function addPicker() {
  $.datetimepicker.setLocale('cs');
  $( "#from" ).datetimepicker({
      timepicker:false,
      format:'d.m.Y',
      value:  '+1970/01/02', //today
      scrollMonth : false,
      scrollInput : false,
      minDate: '+1970/01/02',
      onShow:function( ct ){
          this.setOptions({
              maxDate:$('#to').val()?jQuery('#to').val():false
          })
      }
  });
  $( "#to" ).datetimepicker({
      timepicker:false,
      format:'d.m.Y',
      value:  '+1970/01/08', //a week from today
      scrollMonth : false,
      scrollInput : false,
      onShow:function( ct ){
          this.setOptions({
              minDate:jQuery('#from').val()?jQuery('#from').val():false
          })
      }
  
  });
  }
  $(document).ready(function () {
  addPicker();
  });
  </code></pre>
  
  <p>and html:</p>
  
  <pre><code>&lt;input type="text" name="from" id="from"&gt;
  &lt;input type="text" name="to" id="to"&gt;
  </code></pre>
  
  <p>Please if you have any hints let me know. Thanks.</p>
