Date(); to show when website was last updated?

I’m trying to inform people of how long ago the website was updated on the welcome screen. When I make a revision to the swf I plug in the date in the “Update” field and then it should subtract it from the day the website is viewed.


Now = new Date();
Update = new Date(2006, 7, 1);
Days = (Now-Update);
DaysRound = Math.floor(Days);
if (DaysRound == 1) {
	D = "Day";
} else {
	D = "Days";
}
_root.Status.text = "Updated "+DaysRound+" "+D+" Ago";

So it should say Updated 2 Days Ago (today being the 3rd) but it says Updated -2119732652 Days Ago so I obviously did something wrong… I think I confused myself… the math or syntax is wrong.
