纯JS实现,本来是用于一个程序的插件的。

<span id="showsectime" style="color:#FF0000;"></span>
<script type="text/javascript">
function NewDate(str) { 
	str = str.split('-'); 
	var date = new Date(); 
	date.setUTCFullYear(str[0], str[1] - 1, str[2]); 
	date.setUTCHours(0, 0, 0, 0); 
	return date; 
} 
function showsectime() {
	var birthDay =NewDate("2012-08-01");
	var today=new Date();
	var timeold=today.getTime()-birthDay.getTime();
	
	var sectimeold=timeold/1000
	var secondsold=Math.floor(sectimeold);
	var msPerDay=24*60*60*1000;

	var e_daysold=timeold/msPerDay;
	var daysold=Math.floor(e_daysold);
	var e_hrsold=(daysold-e_daysold)*-24;
	var hrsold=Math.floor(e_hrsold);
	var e_minsold=(hrsold-e_hrsold)*-60;
	var minsold=Math.floor((hrsold-e_hrsold)*-60);

	var seconds=Math.floor((minsold-e_minsold)*-60).toString();
	document.getElementById("showsectime").innerHTML = "网站已安全运行"+daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒";
	setTimeout(showsectime, 1000);
}

showsectime();
</script>
