What is GST in HST?

Hawaii Standard Time is 14 hours behind

Gulf Standard Time is on UTC+4:00 and Hawaii Standard Time is on UTC−10:00 right now. That gap holds all year, because neither zone observes daylight saving.

Scheduling between the two

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

Gulf Standard Time (GST) is used in the UAE and Oman

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