Project templates and date format

I create a project template and when I try to create a new project from the Project Template module system ask about the name and start date.

If you don´t fill the date then system give Error 500

Also the date format is in MM/DD/AAAA but system and user date format are in DD/MM/AAAA. This bug is a really trouble cause my users doesn´t know how to input the date and if they don´t fill it project doesn´t create.
