Add specific price valid TO to product page

[outlet.ee]

In 1.6 I used to have the variable in product.tpl:

{$product->specificPrice.to|date_format:'%e.%-m.%Y'}

It does not work in 1.7. I also tried

{$product.reduction.to}
{$product.specific_price.to}
{$product->specific_price.to}

Is there any way to get it on v1.7 (product-prices.tpl)?
