title: How to set specific timezone in datepicker using jquery only?
body: <p>I've a field and applying datepicker on it using jQuery. </p>
  
  <p>it is currently getting time from system/browser. </p>
  
  <p>I want it to get time from specific time zone e.g America/new_york. </p>
  
  <p>The <code>endDate</code> param is the key to set the calendar, means user should not be able to select the <code>date</code> from future. Currently it is looking like this </p>

  <p>The code snippet is : </p>
  
  <pre><code>jQuery('#convo_start_date').datepicker({
      format: 'dd M yyyy',
       endDate: '+0d',
       autoclose: true,
       showButtonPanel: true, 
       todayBtn: 'linked'
      }).on('change', function () {
          jQuery('.datepicker').hide();
          jQuery('#convo_end_date').attr('value',jQuery('#convo_start_date').val());
      });
  </code></pre>
  
  <p><strong>Question:</strong> Is there any way to set the default specific timezone like America/new_york to do not allow the date from future (according to this specific timezone)?</p>
  
  <p><strong>Note:</strong> I've tried <a href="http://momentjs.com/timezone/docs/#/use-it/" rel="nofollow noreferrer">moment.js</a> but it is conflicting with my current work in jQuery, Is there any params datepicker library providesvto set with timezone?</p>
