HST

HST (Hawaii-Aleutian Standard Time) . In Hawaii and the Aleutian Islands (which are 10 hours behind Coordinated Universal Time (UTC-10)), HST (Hawaii-Aleutian Standard Time) is used. It is interesting to note that Hawaii does not follow Daylight Saving Time and therefore its time is always the same all year round. This renders the islands a good timekeeper of the central Pacific.
