The pilot of a civil aircraft does not need any formal permission to enter or transit a MATZ; however, permission IS needed to enter the included Aerodrome Traffic Zone (ATZ).
ATZs at military aerodromes are normally H24 unless promulgated otherwise.
Nevertheless, it would be sound airmanship and common sense to call 5 min before crossing a MATZ boundary.
