What is WAT in HST?
Hawaii Standard Time is 11 hours behind
West Africa Time is on UTC+1:00 and Hawaii Standard Time is on UTC−10:00 right now. That gap holds all year, because both zones change their clocks together.

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
