网站添加运行时间

以WordPress为例，进入后台→设置→外观→主题编辑器，找到主题页脚，在合适的位置添加以下代码

<div>
<span id="timeDate">载入天数...</span><span id="times">载入时分秒...</span>
<script>
    var now = new Date();
    function createtime() {
        var grt= new Date("08/13/2018 00:00:00");
        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 = "本站已安全运行 "+dnum+" 天 ";
        document.getElementById("times").innerHTML = hnum + " 小时 " + mnum + " 分 " + snum + " 秒";
    }
setInterval("createtime()",250);
</script>
</div>

代码中的“08/13/2018 00:00:00”为你博客成立的时间，可自行修改
