        case "finished":

You should really provide us poor code monkeys with some supplementary code, like your HTML at least so we can see what you're up to! :') — Chris Kempen, Sep 17 '13 at 19:18

Is this along the lines of what you're looking for? First off, some HTML:

<span id="days"></span>
<span id="hours"></span>
<span id="minutes"></span>
<span id="seconds"></span>

Then, some Javascript (together with jQuery!):

setInterval(function(){
    // set whatever future date / time you want here, together with
    // your timezone setting...
    var future = new Date("Sep 20 2014 21:15:00 GMT+0200");
    var now = new Date();
    var difference = Math.floor((future - now) / 1000);

    var seconds = fixIntegers(difference % 60);
    difference = Math.floor(difference / 60);

    var minutes = fixIntegers(difference % 60);
    difference = Math.floor(difference / 60);

    var hours = fixIntegers(difference % 24);
    difference = Math.floor(difference / 24);

    var days = difference;

    $("#seconds").text(seconds + "s");
    $("#minutes").text(minutes + "m");
    $("#hours").text(hours + "h");
    $("#days").text(days + "d");
}, 1000);

function fixIntegers(integer)
{
    if (integer < 0)
        integer = 0;
    if (integer < 10)
        return "0" + integer;
    return "" + integer;
}

I hope this makes sense! Here's a fiddle if you'd like to see the live version in action.
