How to select random date in a date range AS3 - actionscript-3

Question

I'm trying to get a random date in a date range and this is what i have so far but it doesnt seem to be working ??
Where I'm I Going wrong ??
//Gets the date difference
private function differenceBetweenDates(date1:Date, date2:Date):Number{
var MS_PER_DAY:uint = 1000 * 60 * 60 * 24;
var tempDate:Date = new Date(date2.time - date1.time);
var difference:Number =
Math.abs(Math.round((tempDate.time / MS_PER_DAY)));
return difference; }
// gets a random number
function randomRange(max:Number, min:Number = 0):Number {
return Math.round(Math.random() * (max - min) + min); }
protected function getRandomDate:void {
// TODO Auto-generated method stub
var dat1:Date= new Date();
var dat2:Date = new Date(1989, 4, 16)
var num:Number = new Number(differenceBetweenDates(dat2,dat1));
var random:Number= new Number(randomRange(num));
currDate.setDate(dat2.date+random);
getComic(formatDate(currDate));
dat2 = new Date(1989, 4, 16)
}

Answer 1

I found a couple errors in your code.
currDate.setDate(dat2.date+random)
setDate sets the date in the month, not an arbitrary date in time. Also, you want to use dat2.time, not dat2.date.
Should be
currDate.setTime(dat2.time+random)
Here's a slightly different version you might want to try out. I removed the MS_PER_DAY computation, so, you may want to add that back in if you need it, but I found this easier to look at:
public function getRandomTimeBetweenDates(date1:Date, date2:Date):Number
{
return Math.round(Math.random() * (Math.abs(date2.time - date1.time)));
}
public function getRandomDate():Date {
var dat1:Date= new Date();
var dat2:Date = new Date(1989, 4, 16)
dat2.setTime(dat2.time + getRandomTimeBetweenDates(dat2,dat1));
return dat2;
}
