Scheduling between the two
There is no overlap between a nine-to-six working day in Honolulu and one in Lagos — the gap is too wide. A call has to sit early or late for one side. Early morning in Honolulu is the usual compromise, since that is late afternoon or evening in Lagos.
Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
West Africa Time (WAT) is used in Nigeria, Algeria, Angola and Cameroon
