用 js 实现 Emlog 网站运行时间的统计

关于网站运行时间统计代码百度一大堆，博主这里也有一份，也不知道是什么时候找的了，用起来还可以，目前自己也在用，这里就把代码和大家分享一下吧

function show_date_time() { window.setTimeout("show_date_time()", 1000); BirthDay = new Date("10/15/2017 17:47:39"); today = new Date(); timeold = (today.getTime() - BirthDay.getTime()); sectimeold = timeold / 1000; secondsold = Math.floor(sectimeold); msPerDay = 24 * 60 * 60 * 1000; e_daysold = timeold / msPerDay; daysold = Math.floor(e_daysold); e_hrsold = (e_daysold - daysold) * 24; hrsold = Math.floor(e_hrsold); e_minsold = (e_hrsold - hrsold) * 60; minsold = Math.floor((e_hrsold - hrsold) * 60); seconds = Math.floor((e_minsold - minsold) * 60); span_dt_dt.innerHTML = "此破站已苟活:" + daysold + "天" + hrsold + "小时" + minsold + "分" + seconds + "秒"; } show_date_time();
