Getting an exception when trying to use the duration in twig template:
An exception has been thrown during the rendering of a template ("Unable to choose a translation for "1 dzień|%count% dni" with locale "pl" for value "185". Double check that this translation has the correct plural options (e.g. "There is one apple|There are %count% apples").").

The problem is with the translation in: https://github.com/KnpLabs/KnpTimeBundle/blob/fb2241377b985f3d68703309cff0f10e77f1c10e/translations/time.pl.xliff#L69
Will post a fix for this.
