I recently flew CDG COO CDG on the same day (not a MR though) and when i went through immigration, my passport has been stamped with a wrong entry date... dated almost two months before the actual entry date.

I realised this when a security airport officer pointed out my entry date (he was trying to get some money...but this is another story ) , i immediatly showed him my boarding pass stating the correct date.
Anyway the wrong entry date was well before the valid date stated on my visa...
I guess it could have been a serious issue if i stayed longer than i did.


Did anyone encounter similar thing?
How did it happen? Did you have to argue ?
