Turn camera off, remove battery's and sd card. With everything out turn it to the on position for about 2-3. After 2-3 minutes put batterys back in while on the on position. Once he says no card or no memory turn the camera off put sd card back in and test the camera.

Has this to do with difference in europeen and american time and date?
Like europ: DD/MM/YY
american: MM/DD/YY
europ has 24 hours clock america 12 hours with AM and PM.
