BCD Clock

(Binary Coded Decimal)

BCD is a special binary system where EACH individual decimal digit is represented by 4 binary bits. So, the binary count can go no higher than 9 ("10" would be represented by 8 binary digits: 4 for the "1", and 4 for the "0").

Look below for the BCD clock...

Instructions:

1: Copy and paste the following javascript into the BODY section of your page wherever you want the BCD clock to appear:
Select all...

<script language="javascript">
var binclk;
var now;
var ns4 = (document.layers)? true : false;
var ie4 = (document.all && !document.getElementById)? true : false;
var ns6 = (document.getElementById && navigator.appName.indexOf("Netscape")>=0 )? true: false;
function setclock(){
now=new Date();
var txt=getstring(now.getHours()+'')+' : '+getstring(now.getMinutes()+'')+' : '+getstring(now.getSeconds()+'');
if(ns4) txt='<div style="position:absolute; top:0px; left:0px">'+txt+'<\/div>'; 
writeid(binclk, txt);
}
function writeid(id,text){
if(ns4){
id.document.open();
id.document.write('<div style="position:absolute; top:0px; left:0px">'+text+'<\/div>');
id.document.close();
}
else id.innerHTML=text;
}
function getstring(nbr){
while(nbr.length<2) nbr='0'+nbr;
nbr=nbr.split('');
nbr[0]=eval(nbr[0]).toString(2);
nbr[1]=eval(nbr[1]).toString(2);
while(nbr[0].length<4) nbr[0]='0'+nbr[0];
while(nbr[1].length<4) nbr[1]='0'+nbr[1];
return nbr[0]+','+nbr[1];
}
window.onload=function(){
binclk=(ns4)? document.layers['binclk']:(ie4)?document.all['binclk']:document.getElementById('binclk');
setInterval('setclock()', 300);
}
window.onresize=function(){
if(ns4)setTimeout('history.go(0)', 400);
}
</script>
