JQuery Knob - Timer with format HH:mm:dd

Question

I'm trying to set a timer with format HH:mm:dd.

Ex: The time will show "22:25:05" or "00:04:22" with the Horus/minutes/seconds left.

I manged to get it to show the time, but can't make the timer work and do live countdown.

How could i set a timer with this format that will work? Thanks

My code:

var now = moment();
var startDate = "16/03/2016 00:00:00";
var endDate = "16/03/2016 23:59:59";
diffHours = moment.utc(moment(endDate,"DD/MM/YYYY HH:mm:ss").diff(moment())).format("HH");
diffMinutes = moment.utc(moment(endDate,"DD/MM/YYYY HH:mm:ss").diff(moment())).format("mm");
diff = moment.utc(moment(endDate,"DD/MM/YYYY HH:mm:ss").diff(moment())).format("HH:mm:ss");
var percentage_complete = (now - moment(startDate,"DD/MM/YYYY HH:mm:ss")) / (moment(endDate,"DD/MM/YYYY HH:mm:ss") - moment(startDate,"DD/MM/YYYY HH:mm:ss")) * 100;
var percentage_rounded = (Math.round(percentage_complete * 100) / 100); 
jQuery("input.dial").attr("value",percentage_rounded);
jQuery(".dial").knob({
	'readOnly':true,
	'draw' : function () { 
	   	jQuery(this.i).val(diff); 
  	}
});

As per your comment, I have achieved your requirement using jQuery roundSlider plugin.

Based on your requirement i have prepared two demos. One for countdown with single day (24 hours) and another for countdown with long days. Please check the below demos:

For more details about roundSlider check the demos and documentation page.

Edited:

Based on the current date i have updated the demo. Also i have updated an advanced demo with each circle for hours, minutes and seconds.
