What is HST in GST?
Gulf Standard Time is 14 hours ahead

Scheduling between the two
There is no overlap between a nine-to-six working day in Honolulu and one in Dubai — 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 Dubai.
Hawaii Standard Time (HST) is used in all of Hawaii, which does not observe daylight saving
Gulf Standard Time (GST) is used in the UAE and Oman
