Offset 5 hours between free time slot and the details in form

Hi Appointment+ Team !

I managed to translate the plugin in french (part), testing with the sandbox are successful, now I have one last detail rather annoying.

When the customer chooses his schedule in the tables, in its form (and in the email it receives) he finds his details with a lag of five hours!

I set my htaccess file, my ini.php file AND the timezone of my Wordpress admin, as you can see here:

I hope you can enlighten me, I just need a hand on it before ultimately make the system operational.

Thank you for assistance,
