代码显示网站安全运行天数小时分秒

代码1：

本站已安全运行:
<span id="momk"></span>
<script language=javascript>
function show_date_time(){
window.setTimeout("show_date_time()", 1000);
BirthDay=new Date("11-11-2011 11:11:11");//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;}}
