The Castaways on Gilligan's Island (1979)

Plot hole: Mr. Elliott calls his office in Cleveland, Ohio from the secret pay phone in the lobby, but gets no answer. His wife explains it's 4 AM in Cleveland and that's why nobody answered. However, the island is somewhat close to Hawaii and the time difference is 6 hours during summer. The local time on the island would be around 10 PM. Outside however, the sun is shining. Not possible at 10 PM in that region.
