    Help - page, rendering time

    Hi,

    I want display page rendering time.

    Is correct this code? :

    <html>
    <head>
    <SCRIPT>
    var timestampa =new Date;
    var timeInit = timestampa.getT ime();
    </SCRIPT>

    <script language="JavaS cript">
    function displayRenderin gTimestamp() {
    var timestampb=new Date;

    alert (timestampb.get Time() - timeInit );
    }
    </script>
    </head>
    <body topmargin="0" rightmargin="0" leftmargin="0" bottommargin="0 "
    marginwidth="0" marginheight="0 " onLoad="display RenderingTimest amp()">

    Or must be implemented init function to set start timestamp?

    Thanks for any suggestion,
    Fabio

      Your code should do what you want, but I'd use "new Date()"

      <SCRIPT type="text/javascript">
      timeInit = new Date().getTime( );
      function displayRenderin gTimestamp() {
      alert (new Date().getTime( ) - timeInit );
      }
      onload=displayR enderingTimesta mp; //in milliseconds
      </script>

      And you really don't need to use the Date object's "getTime()" method,

      dateObj1-dateObj2 will yield the difference in milliseconds between two
      valid date objects.(Automa tic type conversion)
