之前在网站底部有网站运行时间，有的网友来问是怎么实现的，今天就把我自己用的代码分享下，有需要的直接拿去使用即可。
我们只要将下面的代码添加到网站主题的底部代码添加的位置（一般的WordPress主题都有这个功能），添加后保存即可。如果你的主题没有就添加到 footer.php 中，自行添加即可。
效果如下：

<span id="runtime_span" style="color: #24a0f0;"></span>
<script type="text/javascript">function show_runtime(){window.setTimeout("show_runtime()",1000);X=new
Date("01/04/2020 5:22:00");
Y=new Date();T=(Y.getTime()-X.getTime());M=24*60*60*1000;
a=T/M;A=Math.floor(a);b=(a-A)*24;B=Math.floor(b);c=(b-B)*60;C=Math.floor((b-B)*60);D=Math.floor((c-C)*60);
runtime_span.innerHTML="本站已经运行: "+A+"天"+B+"小时"+C+"分"+D+"秒"}show_runtime();</script>
PS：又额外整理了几款，有需要的直接拿。
