我使用以下Javascript代码在我的网站上显示时间.如何自动进行此更新.

谢谢

<section class="portlet grid_6 leading"> 
<header>
<h2>Time<span id="time_span"></span></h2>
</header>
<script type="text/javascript">
var currentTime = new Date()
var hours = currentTime.getHours()
var minutes = currentTime.getMinutes()
if (minutes < 10){
    minutes = "0" + minutes
}
var t_str = hours + ":" + minutes + " ";
if(hours > 11){
    t_str += "PM";
} else {
   t_str += "AM";
}
document.getElementById('time_span').innerHTML = t_str;
</script>
</section>

我有一个显示日期和时间的脚本.

如何添加内容以使其自动更新而不是页面刷新.

这是脚本:

<?php
$hourdiff = 0; // Replace the 0 with your timezone difference (;
$site = date("l, d F Y g:i a",time() + ($hourdiff * 3600));
echo $site;
?>

谁能帮忙.谢谢.
