Get value from datetimepicker in code behind c#

Question

I'm doing some Sharepoint webparts and i'm trying to use a jquery datetimepicker, but i can't quite retrieve the value from the datetimepicker in the C# code behind. Here is my script :

   <input type="hidden" id="StartDateHiddenField" name="StartDateHiddenField" value=""/>
     <script type="text/javascript">
         $(document).ready(function () {
             $(".datepicker1").datepicker({
                 changeMonth: true,
                 changeYear: true,
                 dateFormat: "dd-mm-yy",
                 showButtonPanel: false,
                 onClose: function (dateText, inst) {
                     $(this).datepicker('setDate', new Date(inst.selectedYear, inst.selectedMonth, 1));
                     $('#StartDateHiddenField').val($(this).datepicker("getDate"));
                 }

             });
        });
    </script>

In code behind :

 var test = Page.Request.Form["StartDateHiddenField"];
 var startTime = DateTime.Parse(Page.Request.Form["StartDateHiddenField"]);

test value according to debugger is, for exemple :

"Sat Jul 01 2017 00:00:00 GMT+0200 (Romance Daylight Time)"

How can i get proper values from DateTime.Parse ?

感谢ADyson，一个解决方案是使用$(this).datepicker("getDate").toISOString()
