            <script type = "text/javascript">

                function renderTime() {

            var currentTime() = new Date(); 
            var diem = "AM"
            var h = currentTime.getHours();
            var m = currentTime.getMinutes();
            var s = currentTime.getSeconds();


            if (h ==0){
                h = 12
            }   else if (h>12) {
                h = h - 12; 
                diem = "PM";

            }

            if (h<10){
                h = "0" + h;

            }

            if (m<10){

你有很多语法错误。尝试改变：

var currentTime() = new Date();至var currentTime = new Date();和

setTimeout('renderTime()',1000);至setTimeout(renderTime,1000);

你也有一些缺失的分号，但是这两个变化会使它起作用，正如你在fiddle中看到的那样。
