看到很多站长，都喜欢在自己网站的底部加入“本站已稳定运行多少天”的小功能
不用太在意细节。这个数字直接用JS就能实现。

function showsectime() {

var birthDay = NewDate("2019-05-13");

// 这里修改站点开启日期

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 = "稳定运行 :" + daysold + "天" + hrsold + "小时" + minsold + "分" + seconds + "秒";

setTimeout(showsectime, 1000);

}

showsectime();

html代码

<span id="showsectime"></span>

运行结果
