Countdown to a specific hour?

I have used a countdown window to the opening of a new restaurant.

The timer counts down to midnight but the restaurant opens at 10 am on the 18th.

Is there a way to countdown to a specific time?

Here’s the Action script I’m using…

this.onEnterFrame = function() {

var today:Date = new Date ();
var currentYear = today.getFullYear();
var currentTime = today.getTime();

var targetDate:Date = new Date(currentYear,11,18);
var targetTime = targetDate.getTime();

var timeLeft = targetTime - currentTime;

var sec = Math.floor(timeLeft/1000);
var min = Math.floor(sec/60);
var hrs = Math.floor(min/60);
var days = Math.floor(hrs/24);
sec = string(sec % 60);
if (sec.length < 2) {
	sec = "0" + sec;
}
min = string(min % 60);
if (min.length < 2 ) {
	min = "0" + min;
}
hrs = string(hrs % 24);
if (hrs.length < 2 ) {
	hrs = "0" + hrs;
}
days = string(days);

var counter:String = days + ":" + hrs + ":" + min + ":"+ sec;
time_txt.text = counter;

}

thanks
