Calculate date no more than 365 from now

[freakness883]

I was hoping to use the following code to make sure that a date entered is not more than 365 from now:

[code]!(floor((time() - strtotime($expiration_date))/86400) > 365) [/code]

This condition fails. Does anyone know why?

It depends how you're using it because you have !

Example:
[code]
$expiration_date = '01/01/2006';

if ((floor((time() - strtotime($expiration_date))/86400) > 365)) {
    echo 'outside of 365 days';
} else {
    echo 'within 365 days';  // displays this

}
[/code]

Using 07/12/2005 date with the example code will display that it's outside the 365 day window.
