Я использую такой код
<script>
var sec=00;
var min=15;
var inter;
function refresh(){
sec--;
if(sec==-01){sec=59; min=min-1;}
else{min=min;}
if(sec<=9){sec="0" + sec;}
time=(min<=9 ? "0" + min : min) + ":" + sec;
if(document.getElementById){timer.innerHTML=time;}
inter=setTimeout("refresh()", 1000);
if(min=='00' && sec=='00'){
sec="00";min=='00'; clearInterval(inter);
}
}
$(document).ready(function(){
refresh();
});
</script>
