i attempting follow guide, have had change few things far.http://jsfiddle.net/tc6gr/37/

$('#start_time').datetimepicker({     format: 'dd-mm-yyyy h:mm:ss a', }).on("dp.change", function (e) {     alert(e.date);     $('#start-time-before').html(e.date); // log     var timezoned = new date(e.date.settime(e.date.gettime() + (e.date.gettimezoneoffset() * 60000)));     $('#end_time').datetimepicker('setstartdate', timezoned);     $('#start_time').datetimepicker('setdate', timezoned);     $('#start-time-adjusted').html(timezoned); // log }); 

you should try instead.

 var offset = e.date.gettimezoneoffset() * 60000;  var = e.date.gettime();  var utc = + offset;  var timezoned = new date(utc);
