I'm doing a countdown system and I'm using "The Final Countdown jQuery"
$('#clock').countdown('2015/02/16', function(event) {
$(this).html(event.strftime('%D dias %H:%M:%S'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script><scriptsrc="http://mindvelopers.com/jquery.countdown.min.js"></script>
<div id="clock"></div>
My problem is that I need to add +21 hours to each event (to the result), but I can not add it the way this function is done.
