Is it possible to Create an alarm clock with JavaScript? I have a set number of alarm times and when the time reaches that time it will issue a beep or load a mp3.

<!-- THREE STEPS TO INSTALL ALARM CLOCK:

1. Copy the coding into the HEAD of your HTML document
2. Add the onLoad event handler into the BODY tag
3. Put the last coding into the BODY of your HTML document -->

<!-- STEP ONE: Paste this code into the HEAD of your HTML document -->

<HEAD>

<SCRIPT LANGUAGE="JavaScript">
<!-- Original: John Caranta (caranta@netzero.net) -->

<!-- This script and many more are available free online at -->
<!-- The JavaScript Source!! http://javascript.internet.com -->

<!-- Begin
var alarmTime;
var curTime;
var check = new Date();
var hourNum;
var minNum;
function GetTime() {
var dt = new Date();
document.clock.local.value = IfZero(dt.getHours()) + ":" + IfZero(dt.getMinutes());
setTimeout("GetTime()", 1000);
curTime = (IfZero(dt.getHours()) + ":" + IfZero(dt.getMinutes()));
}
function IfZero(num) {
return ((num <= 9) ? ("0" + num) : num);
}
function alarmSet() {
hourNum = document.clock.hourOpt[document.clock.hourOpt.selectedIndex].value;
minNum = document.clock.minOpt[document.clock.minOpt.selectedIndex].value;
alarmTime = hourNum + ":" + minNum;
}
function alarmOn() {
if (alarmTime == curTime) {
document.all.sound.src = document.clock.alarmSound.value;
}
else {
setTimeout("alarmOn()", 1000)
}
}
function alarmOff() {
document.all.sound.src = "";
alarmTime="";
}
function snooze() {
document.all.sound.src = "";
var snoozeL = parseInt(document.clock.snoozeOpt[document.clock.snoozeOpt.selectedIndex].value);
var snooze = new Date();
alarmTime = IfZero(snooze.getHours()) + ":" + IfZero(snooze.getMinutes() + snoozeL);
alarmOn();
}
// End -->
</script>
<bgSound src="" id="sound">
</HEAD>

<!-- STEP TWO: Insert the onLoad event handler into your BODY tag -->

<BODY onLoad="GetTime()">

<!-- STEP THREE: Copy this code into the BODY of your HTML document -->
