Countdown Question

Here’s my problem I have done the tutoral for the countdown banner and have it working. My problem is I would like it to go to a specific time not just a date. The code below is what I have. If anyone can help me with this I would greatly appreciate it.

stop();

currentDate = new Date();
thisYear = currentDate.getFullYear();

eventDate = new Date(thisYear, 1, 20);
eventMillisecs = eventDate.getTime();

counter.onEnterFrame = function(){

currentDate = new Date();
currentMillisecs = currentDate.getTime();


this.msecs = eventMillisecs - currentMillisecs;


if (this.msecs <= 0){
	
	play();
	
	return;
}


this.secs = Math.floor(this.msecs/1000); 
this.mins = Math.floor(this.secs/60); 
this.hours = Math.floor(this.mins/60); 
this.days = Math.floor(this.hours/24);


this.msecs = string(this.msecs % 1000);
this.secs = string(this.secs % 60);
this.mins = string(this.mins % 60);
this.hours = string(this.hours % 24);
this.days = string(this.days);


while (this.msecs.length < 3) this.msecs = "0" + this.msecs;
if (this.secs.length < 2) this.secs = "0" + this.secs;
if (this.mins.length < 2) this.mins = "0" + this.mins;
if (this.hours.length < 2) this.hours = "0" + this.hours;
while (this.days.length < 3) this.days = "0" + this.days;


for(movie in this){
	if (this[movie]._parent == this) this[movie].evaluateFrameFrom(this);
}

};

MovieClip.prototype.evaluateFrameFrom = function(variableClip){

var nameArray = this._name.split("_");

var numberSet = variableClip[nameArray[0]];

var character = number(nameArray[1]);

var frame = 1 + number(numberSet.charAt(character));

if (this._currentframe != frame) this.gotoAndStop(frame);

};
