List of localized months

I'm trying to print a list of localized month names in my rails app. I set my locale to it-IT, created an it-IT.yml translation file with the translated month names, but it doesn't seem to work.

When I use date_select I can see the trasnlated months, therefore my
yml file and my locale should be ok, but when I try something like"%B") or Date::MONTHNAMES i always get the english month names.

Date's strftime & Date's MONTHNAME constants just aren't localized
(I18n.localize has a localized strftime for you)
