Change from Countdown script to CountUp in latest Deal

Hello,
I would like change time in Latest Deals Box.
Deafulty is Countdown Time, I would like get CountUp from specific date.

Eg.: Specific date:
and Count up to time when Latest Deals will be updated by new product.

I found in JS:
/** COUNT DOWN **/

$('[data-countdown]').each(function() {

var $this = $(this), finalDate = $(this).data('countdown');

$this.countdown(finalDate, function(event) {

var fomat ='%H%M%S';

$this.html(event.strftime(fomat));

});

});

if($('.countdown-lastest').length >0){

var labels = ['Years', 'Months', 'Weeks', 'Days', 'Hrs', 'Mins', 'Secs'];

var layout = '{dnn} Days:{hnn} Hrs:{mnn} Mins:{snn} Secs';

$('.countdown-lastest').each(function() {

var austDay = new Date($(this).data('y'),$(this).data('m') - 1,$(this).data('d'),$(this).data('h'),$(this).data('i'),$(this).data('s'));

$(this).countdown({

until: austDay,

labels: labels,

layout: layout

});

});

}

and I can't edit it like is on author web page http://keith-wood.name/countdown.html in CountUp Tab... where weh ave a code: $('#sinceCountdown').countdown({since: startYear, format: 'YOWDHMS', description: 'Since New Year'});

Can You Help Me ?
