网站运行时间代码

给网站添加一个运行时间代码，可以增加网站的运行长久的感觉

样式1

<span>
本站已不间断运行
</span>
<span id="span_dt_dt">
</span>
<script>
/*建站时间*/
function show_date_time() {
window.setTimeout("show_date_time()", 1e3);
var BirthDay = new Date("2020/03/01"),//初始日期
today = new Date,
timeold = today.getTime() - BirthDay.getTime(),
msPerDay = 864e5,
e_daysold = timeold / msPerDay,
daysold = Math.floor(e_daysold),
e_hrsold = 24 * (e_daysold - daysold),
hrsold = Math.floor(e_hrsold),
e_minsold = 60 * (e_hrsold - hrsold),
minsold = Math.floor(60 * (e_hrsold - hrsold)),
seconds = Math.floor(60 * (e_minsold - minsold));
span_dt_dt.innerHTML = daysold + "天" + hrsold + "小时" + minsold + "分" + seconds + "秒";
}
show_date_time();
</script>

样式2

<span id="nowTime"></span>
<script type="text/javascript">
//获取系统时间
var newDate = '';
getLangDate();
//值小于10时，在前面补0
function dateFilter(date){
if(date < 10){return "0"+date;}
return date;
}
function getLangDate(){
var dateObj = new Date(); //表示当前系统时间的Date对象
var year = dateObj.getFullYear(); //当前系统时间的完整年份值
var month = dateObj.getMonth()+1; //当前系统时间的月份值
var date = dateObj.getDate(); //当前系统时间的月份中的日
var day = dateObj.getDay(); //当前系统时间中的星期值
var weeks = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"];
var week = weeks[day]; //根据星期值，从数组中获取对应的星期字符串
var hour = dateObj.getHours(); //当前系统时间的小时值
var minute = dateObj.getMinutes(); //当前系统时间的分钟值
var second = dateObj.getSeconds(); //当前系统时间的秒钟值
var timeValue = "" +((hour >= 12) ? (hour >= 18) ? "晚上" : "下午" : "上午" ); //当前时间属于上午、晚上还是下午
newDate = dateFilter(year)+"年"+dateFilter(month)+"月"+dateFilter(date)+"日 "+" "+dateFilter(hour)+":"+dateFilter(minute)+":"+dateFilter(second);
document.getElementById("nowTime").innerHTML = timeValue+"好！当前时间为： "+newDate+"　"+week;
setTimeout("getLangDate()",1000);
}
