este código não foi criado nem modificado por mim, a fonte não sei qual é porque apenas tinha aqui no pc.

mas para alterar as cores do relógio apenas têm de alterar estes campos

fCol='000000';//face colour.
sCol='ff0000';//seconds colour.
mCol='000000';//minutes colour.
hCol='000000';//hours colour.

Bem, hoje comecei a aprender javascript e como primeiro programa decidi fazer um relógio que achasse ser o mais eficiente possível. Este foi o resultado final:

// JavaScript Document

// clock.js a clock that update only when it's really required and what is required.
// What i mean with this is that for exemplo at the time 10:11:00 the clock just update the seconds and the minutes, not que hours.
// the close doesn't update at a fixed time like almost every clocks, just update when the output is different form the actual output
//
// Author: João Santos (jarsantos@gmail.com)
//
// Everyone can use it and change it, but keep the credits please
// Enjoy!

var weekDays = new Array("Sunday", "Monday", "Thursday", "Wednesday", "Tuesday", "Friday", "Saturday")
var months = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December")

function formatClock(int)
{
if(int < 10)
{
	int = '0'+int
}

return int
}

function startClock()
{	
var date = new Date()

var time = new Array(date.getHours(), formatClock(date.getMinutes()), formatClock(date.getSeconds()))

var weekDay = date.getDay()
var month = date.getMonth()
var day = new Array(weekDay, weekDays[weekDay], date.getDate(), month, months[month], date.getFullYear())

return new Array(time, day)
}

function updateClock(passado)
{
time = passado[0]
day = passado[1]
clockInfo = passado[2]

date = new Date()

time[2] = formatClock(date.getSeconds())

if(time[2] == '00')
{
	time[1] = formatClock(date.getMinutes())

	if(time[1] == '00')
	{
		time[0] = date.getHours()

		if(time[0] == 0)
		{
			day[0] = date.getDay()
			day[1] = weekDays[day[0]]

			day[2] = date.getDate()

			if(day[2] == 1)
			{
				day[3] = date.getMonth()
				day[4] = months[day[3]]

				if(day[3] == 1)
				{
					day[5] = date.getFullYear();
				}
			}
		}
	}
}

document.getElementById('clock').innerHTML=time.join(':')+'<br />'+day[1]+', '+day[2]+' '+day[4]+' '+day[5]

t=setTimeout('updateClock(new Array(time, day))',1000-(new Date().getMilliseconds()))	
}

<body onload="updateClock(startClock())">
<div id="clock"></div>
</body>
</html>

Espero que gostem, deu-te um grande trabalho, mas também é um gozo ver o programa a trabalhar tão bem.

Se testarem ao lado do que já foi colocado aqui neste tópico vão ver que este é mais rápido a actualizar e mais eficiente (não usa tanto o CPU)
