wordpress网站页脚添加稳定运行时长的代码

直接上代码，备忘：

博客已勉强运行：

<SCRIPT language=javascript>function show_date_time(){

window.setTimeout("show_date_time()", 1000);

BirthDay=new Date("1/1/2015 00:00:00");

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=''+daysold+' 天 '+hrsold+' 时 '+minsold+' 分 '+seconds+' 秒';

}

show_date_time();</script>
