No disrespect meant here but Shunter is correct despite the straight talking, it is your responsibility to know the regulations regarding your licence and each country of issue has different rules. Most licences are issued in accordance with ICAO but it is the issuing authority that is important.
It is as important as knowing your aeroplane otherwise how would you know if you are legal.
If it is FAA read the FAR-AIM, if it is JAA read LASORS etc.
