Countdown Question 2

The code that I have works perfect in Flash MX. Can anyone help me make this work in Flash 5? I know that sounds ridiculous, but that is what my boss is requesting. Brainy you were a ton of help yesterday thanks again. Below is the AS that I have currently. Thanks in advance to anyone who can help me.
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);

}
};

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);
};
