France and Italy doesn't electronically record entries and exits. However, if your passport is not from the EU/EFTA, Andorra, Monaco or San Marino, you should have entry and exit stamps in your passport, which prove the dates.
Poland does record entries and exits if the entry/exit to/from the Schengen Area was through there. However, again, if not from the EU/EFTA, Andorra, Monaco or San Marino, you'll have stamps in your passport.
