显示当前时间的javascript

我有以下javascript代码来显示当前日期和时间：

<script type="text/javascript">
tday  =new Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");
tmonth=new Array("January","February","March","April","May","June","July","August","September","October","November","December");

function GetClock(){
d = new Date();
nday   = d.getDay();
nmonth = d.getMonth();
ndate  = d.getDate();
nyear = d.getYear();
nhour  = d.getHours();
nmin   = d.getMinutes();
nsec   = d.getSeconds();

if(nyear<1000) nyear=nyear+1900;
if(nhour ==  0) {ap = " AM";nhour = 12;} 
else if(nhour <= 11) {ap = " AM";} 
else if(nhour == 12) {ap = " PM";} 
else if(nhour >= 13) {ap = " PM";nhour -= 12;}

if(nmin <= 9) {nmin = "0" +nmin;}
if(nsec <= 9) {nsec = "0" +nsec;}


document.getElementById('clockbox').innerHTML=""+tday[nday]+", "+tmonth[nmonth]+" "+ndate+", "+nyear+" "+nhour+":"+nmin+":"+nsec+ap+"";
setTimeout("GetClock()", 1000);
}
window.onload=GetClock;
</script>
<div id="clockbox"></div>  

tday=新数组（“星期日”、“星期一”、“星期二”、“星期三”、“星期四”、“星期五”、“星期六”）；
tmonth=新数组（“一月”、“二月”、“三月”、“四月”、“五月”、“六月”、“七月”、“八月”、“九月”、“十月”、“十一月”、“十二月”）；
函数GetClock（）{
d=新日期（）；
nday=d.getDay（）；
nmonth=d.getMonth（）；
ndate=d.getDate（）；
nyear=d.getYear（）；
nhour=d.getHours（）；
nmin=d.getMinutes（）；
nsec=d.getSeconds（）；
如果（nyear
if（ap='AM'）{
ap=“”；
}否则{
ap=“”；
}

在自定义两个图像标记的src'es之后，将其粘贴在
document.getElementById
行之前。
因此，本质上，您是在问如何用html创建图像？非常感谢！您太快了！
if (ap == ' AM') {
    ap = " <img src='/path/to/am.png'>";
} else {
    ap = " <img src='/path/to/pm.png'>";
}
