Effects of standard time on television broadcasting
Most cable providers in Hawaii carry the west coast feed of television networks, though since Hawaii doesn't use daylight savings time, all programs air three hours earlier than what they were advertised as for a majority of the year. Even when the rest of the country is on standard time, programs air two hours earlier. So from November to March, programs advertised as airing at 8:00 really air at 6:00 in Hawaii. And from March to November, a program advertised as airing at 8:00 will air at 5:00.
