    As others have mentioned, this is not going to be terribly accurate. But this should work reasonably.

    In your <head>, i.e., as early as possible:

    <script>
   var startTime = (new Date()).getTime();
</script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
   $(window).load(function () {
       var endTime = (new Date()).getTime();
       var millisecondsLoading = endTime - startTime;
       // Put millisecondsLoading in a hidden form field
       // or Ajax it back to the server or whatever.
   });
</script>

    The key is this behavior, from the jQuery docs:

    When bound to the window element, the
    event fires when the user agent
    finishes loading all content within a
    document, including window, frames,
    objects and images.
