Up until October of 1983, Alaska was separated into four time zones. It has since been two -- with the bulk of the state in the above mentioned Alaska Time Zone. The exception to this is the portion of Alaska's Aleutian Islands located west of 169° 30′ W longitude which fall under Hawaii-Aleutian Time Zone . The main islands in this zone (from East to West) are Atka, Adak, and Attu. The Hawaii-Aleutian Time Zone is 10 hours off of Greenwich Mean Time and does not observe Daylight Savings Time.
