Hawaii-Aleutian time zone
From Wikipedia, the free encyclopedia
The Hawaii-Aleutian Time Zone observes Hawaii-Aleutian Standard Time (HST), by subtracting ten hours from Coordinated Universal Time (UTC-10). The clock time in this zone is based on the mean solar time of the 150th degree meridian west of the Greenwich Observatory.
The zone also includes Alaska's Aleutian Islands west of 169° 30′ west, along with Hawaii. The portion in the Aleutian islands observes DST while Hawaii does not.
Hawaii used a standard time of GMT-10:30 from 1900 until 1947, when clocks were changed to the present -10:00 zone.[1]
