$orderBy = Tools::getProductsOrder('by', Tools::getValue('orderby'));

Replace with
$orderByValues = array(0 => 'date_add', 1 => 'price', 2 => 'name', 3 => 'date_upd', 4 => 'position'); $orderWayValues = array(0 => 'DESC', 1 => 'ASC');
Find
$products = Product::getProducts(intval($cookie->id_lang), 0, ($number > 10 ? 10 : $number), $orderBy, $orderWay, $id_category, true);
Replace with
$products = Product::getNewProducts(intval($cookie->id_lang), 0, 10, false, 'date_add', 'DESC');
Now we need to add the pubdate for the product to the rss
Find
$image = Image::getImages((int)($cookie->id_lang), $product['id_product']);
echo "\t\t<item>\n";
Add after on a new line
echo "\t\t\t<pubDate><![CDATA[".$product['date_add']." ]]></pubDate>\n";
