How to output date select in another language?

Hello,

I’ve been trying to output date selects in another language without
success.

http://wiki.rubyonrails.com/rails/pages/HowToOutputDatesInAnotherLanguage

The link above describes a way to output dates in whatever language you
want (I tested the example given and it worked fine) but it doesn’t seem
to work for date selects.

Any ideas or workarounds ?

Thanks in advance,
Jonathan.
