<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js?ver=1.3.2' type='text/javascript'></script>

7. Tambahkan script ini, di bawah script jQuery tadi.

<script type='text/javascript'> //<![CDATA[ $(function(){ // *** // Scrolling background // *** // height of background image in pixels var backgroundheight = 4000; // get the current minute/hour of the day var now = new Date(); var hour = now.getHours(); var minute = now.getMinutes(); // work out how far through the day we are as a percentage - e.g. 6pm = 75% var hourpercent = hour / 24 * 100; var minutepercent = minute / 30 / 24 * 100; var percentofday = Math.round(hourpercent + minutepercent); // calculate which pixel row to start graphic from based on how far through the day we are var offset = backgroundheight / 100 * percentofday; // graphic starts at approx 6am, so adjust offset by 1/4 var offset = offset - (backgroundheight / 1); function scrollbackground() { // decrease the offset by 1, or if its less than 1 increase it by the background height minus 1 offset = (offset < 1) ? offset + (backgroundheight - 1) : offset - 1; // apply the background position $('body').css("background-position", "50% " + offset + "px"); // call self to continue animation setTimeout(function() { scrollbackground(); }, 70 ); } // Start the animation scrollbackground(); }); //]]> </script>

}
