  <script type="text/javascript"> 
  var gmtOffset
  function timezone()  
  {  
    var localTime = new Date();  
    //this one will give you the GMT offset  
    gmtOffset = localTime.getTimezoneOffset()/60 * (-1);  
  }  
  </script>

然后将变量gmtOffset发回到您的应用程序中.

then post back the variable gmtOffset to your application.
