看到很多的博客站点上都是有网站运行时间统计的代码，之前有学过JS语言，之后上网上借鉴了一下网上大佬写的代码。就是一个简单的运行时间的减法运算，才用了JS的事件函数，获取当前时间等等操作，最后给大家看一下代码及效果图片吧！

网站统计时间效果
代码语言：javascript复制<span id="sitetime"></span>
<script language=javascript>
function siteTime(){
window.setTimeout("siteTime()", 1000);
var seconds = 1000;
var minutes = seconds * 60;
var hours = minutes * 60;
var days = hours * 24;
var years = days * 365;
var today = new Date();
var todayYear = today.getFullYear();
var todayMonth = today.getMonth() 1;
var todayDate = today.getDate();
var todayHour = today.getHours();
var todayMinute = today.getMinutes();
var todaySecond = today.getSeconds();
/* Date.UTC() -- 返回date对象距世界标准时间(UTC)1970年1月1日午夜之间的毫秒数(时间戳)
year - 作为date对象的年份，为4位年份值
month - 0-11之间的整数，做为date对象的月份
day - 1-31之间的整数，做为date对象的天数
hours - 0(午夜24点)-23之间的整数，做为date对象的小时数
minutes - 0-59之间的整数，做为date对象的分钟数
seconds - 0-59之间的整数，做为date对象的秒数
microseconds - 0-999之间的整数，做为date对象的毫秒数 */
var t1 = Date.UTC(2017,11,11,16,16,16); //北京时间2016-12-1 00:00:00
var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond);
var diff = t2-t1;
var diffYears = Math.floor(diff/years);
var diffDays = Math.floor((diff/days)-diffYears*365);
var diffHours = Math.floor((diff-(diffYears*365 diffDays)*days)/hours);
var diffMinutes = Math.floor((diff-(diffYears*365 diffDays)*days-diffHours*hours)/minutes);
var diffSeconds = Math.floor((diff-(diffYears*365 diffDays)*days-diffHours*hours-diffMinutes*minutes)/seconds);
document.getElementById("sitetime").innerHTML=" 已运行 " diffYears " 年 " diffDays " 天 " diffHours " 小时 " diffMinutes " 分钟 " diffSeconds " 秒";
}
siteTime();
