为网站添加一个运行时间

将下面代码加到footer的合适位置自行调整

代码：

<!-- 开站时间开始 --> 
 <a id="timeDate">载入天数...</a><a id="times">载入时分秒...</a> <script language="javascript"> 
 var now = new Date();
 function createtime(){
 var grt= new Date("04/17/2022 00:00:00");/*---这里是网站的启用时间--*/
 now.setTime(now.getTime()+250);
 days = (now - grt ) / 1000 / 60 / 60 / 24;
 dnum = Math.floor(days);
 hours = (now - grt ) / 1000 / 60 / 60 - (24 * dnum);
 hnum = Math.floor(hours);
 if(String(hnum).length ==1 ){hnum = "0" + hnum;}
 minutes = (now - grt ) / 1000 /60 - (24 * 60 * dnum) - (60 * hnum);
 mnum = Math.floor(minutes);
 if(String(mnum).length ==1 ){mnum = "0" + mnum;}
 seconds = (now - grt ) / 1000 - (24 * 60 * 60 * dnum) - (60 * 60 * hnum) - (60 * mnum);
 snum = Math.round(seconds);
 if(String(snum).length ==1 ){snum = "0" + snum;}
 document.getElementById("timeDate").innerHTML = "稳定运行"+dnum+"天";
 document.getElementById("times").innerHTML = hnum + "小时" + mnum + "分" + snum + "秒";
 }
 setInterval("createtime()",250); 
</script> 
<!-- 开站时间结束 -->
