Scheduling between the two

There is no overlap between a nine-to-six working day in Lagos and one in Honolulu — the gap is too wide. A call has to sit early or late for one side. Early morning in Lagos is the usual compromise, since that is late afternoon or evening in Honolulu.

West Africa Time (WAT) is used in Nigeria, Algeria, Angola and Cameroon

Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
