网站运行时间代码

样例一

<span id="runtime_span"></span>
<script type="text/javascript">
function show_runtime(){window.setTimeout("show_runtime()",1000);
X=new Date("7/16/2018 5:22:00");
Y=new Date();
T=(Y.getTime()-X.getTime());
M=24*60*60*1000;
a=T/M;A=Math.floor(a);
b=(a-A)*24;B=Math.floor(b);
c=(b-B)*60;C=Math.floor((b-B)*60);
D=Math.floor((c-C)*60);
runtime_span.innerHTML="本站勉强运行: "+A+"天"+B+"小时"+C+"分"+D+"秒"}show_runtime();
</script>

样例二

<span>本站已安全运行:</span>
<span id="momk"></span>
<script language=javascript>
function show_date_time(){
window.setTimeout("show_date_time()", 1000);
BirthDay=new Date("05-06-2016 12:12:24");//建站日期
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=(daysold-e_daysold)*-24;
hrsold=Math.floor(e_hrsold);
e_minsold=(hrsold-e_hrsold)*-60;
minsold=Math.floor((hrsold-e_hrsold)*-60);
seconds=Math.floor((minsold-e_minsold)*-60);
momk.innerHTML=daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒" ;
}
show_date_time();
</script>
<style>
#momk{animation:change 10s infinite;font-weight:800; }
@keyframes change{0%{color:#5cb85c;}25%{color:#556bd8;}50%{color:#e40707;}75%{color:#66e616;}100% {color:#67bd31;}}
</style>

样式三

<span>
    本站已运行
</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("2018/03/01"),
        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>
