Cookie getMaxAge

I can't retrieve cookie maxage it always returns -1

Creating cookie:

Cookie securityCookie = new Cookie("sec", "somevalue");
securityCookie.setMaxAge(EXPIRATION_TIME);

Retrieve cookie:

Cookie[] cookies = request.getCookies();
if (cookies != null) {
    for(int i=0; i<cookies.length; i++) {
        Cookie cookie = cookies[i];
        if ("sec".equals(cookie.getName())){
            int age = cookie.getMaxAge();
        }
    }
}

i am always getting age = -1

also when i check in firefox cookie expiration i see strange date.

Thx
