East Africa Time is 13 hours ahead
Hawaii Standard Time is on UTC−10:00 and East Africa Time is on UTC+3:00 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 Honolulu and one in Nairobi — 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 Nairobi.
Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
East Africa Time (EAT) is used in Kenya, Tanzania, Uganda and Ethiopia
