What is HST in GST?

Gulf Standard Time is 14 hours ahead

Hawaii Standard Time is on UTC−10:00 and Gulf Standard Time is on UTC+4:00 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 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
