JavaScript Date Objects: Universal Coordinated Time - Using the UTC() Function
(Page 4 of 4 )
Another way to get the milliseconds (and if you are a savvy programmer, month, year, etc) from January 01, 1970, is to use the UTC() function. Here it is:
<html>
<body>
<script type="text/javascript">
var wow = Date.UTC(2007,12,15);
document.write("The amount of milliseconds that have passed ");
document.write(" from 01/01/1970 to December 15, 2007: ");
document.write(wow);
</script>
</body>
</html>
The result:
The amount of milliseconds that have passed from 01/01/1970 to December 15, 2007: 1200355200000
And you can of course convert the milliseconds to days, hours, minutes, months, years, decades, centuries, bicentennials, millennia, and so forth.
Creating a JavaScript Clock for Your Web Page
You can make a clock for your web page for those web site visitors that constantly need to know what time it is. You know, like rappers, who are always asking what time it is at their concerts. I mean, they have all that money to drink Crystal, pimp out those rims, and get jiggy wid it. Why can't they just buy a Casio so they don't have to interrupt their concerts all the time?
All you rappers out there...this code is for you:
<html>
<head>
<script type="text/javascript">
document.write("Throw yo hands in da air and swang em like you only care a little");
document.write("<br />")
document.write("<br />")
document.write("The Current Time is: ")
function startTime()
{
var thedate=new Date();
var h=thedate.getHours();
var m=thedate.getMinutes();
var s=thedate.getSeconds();
m=checkTime(m);
s=checkTime(s);
document.getElementById('txt').innerHTML=h+":"+m+":"+s;
t=setTimeout('startTime()',500);
}
function checkTime(i)
{
if (i<10)
{
i="0" + i;
}
return i;
}
</script>
</head>
<body onload="startTime()">
<div id="txt"></div>
</body>
</html>
Well that's it for this one. Come back and visit us next time when we continue the Date Object discussion.
