网站底部显示当前时间的代码，放到想要显示的地方

代码：

<span id=localtime></span><script type="text/javascript">function showLocale(objD)
{var str,colorhead,colorfoot;var yy = objD.getYear();
if(yy<1900) yy = yy+1900;
        var MM = objD.getMonth()+1;
    if(MM<10) MM = '0' + MM;
    var dd = objD.getDate();
    if(dd<10) dd = '0' + dd;
    var hh = objD.getHours();
    if(hh<10) hh = '0' + hh;
    var mm = objD.getMinutes();
    if(mm<10) mm = '0' + mm;
    var ss = objD.getSeconds();
    if(ss<10) ss = '0' + ss;
    var ww = objD.getDay();
    if  ( ww==0 )  colorhead="<font color=\"#FF3030\">";
    if  ( ww > 0 && ww < 6 )  colorhead="<font color=\"#FF3030\">";
    if  ( ww==6 )  colorhead="<font color=\"#FF3030\">";
    if  (ww==0)  ww="星期日";
    if  (ww==1)  ww="星期一";
    if  (ww==2)  ww="星期二";
    if  (ww==3)  ww="星期三";
    if  (ww==4)  ww="星期四";
    if  (ww==5)  ww="星期五";
    if  (ww==6)  ww="星期六";
    colorfoot="</font>"
    str = colorhead + yy + "/" + MM + "/" + dd + "丨" + hh + ":" + mm + ":" + ss + "丨" + ww + colorfoot;
    return(str);}function tick()
{var today;today = new Date();document.getElementById("localtime").innerHTML = showLocale(today);window.setTimeout("tick()", 1000);}
tick();</script>

展示效果：不是很美观，意义不是很大，做个代码记录吧。
