A New Challenge! Changing The Date Language In Non Unicode App...

[Serghej]

Hi everybody!
I've a difficult task!
I'm Italian and I belong an application that doesn't support inside of it the changing of date language, so I went to Computer Preferences, International, Format and selected the Language [english or english (computer)] and the date changed in the sys tray but not inside this software that is still in Italian....
Someone has ideas how to do it???
Thanks you all for trying!

Ciao da Roma, Italia.
