Player Language

Hi everybody ! I’m using Xibo on a TV where I have to display the date in french. I’m using the Digital Clock module. I use this : Bienvenue, nous sommes le [dddd] [DD] [MMMM].
On the layout preview it shows this :

Bienvenue, nous sommes le mercredi 25 septembre.

But on the TV it shows :

Bienvenue, nous sommes le wednesday 25 september.

I have checked the CMS/Player settings but everything is set on french/fr_FR. Is there a solution to display the date in french on the player ? Regards from France.
