Alaska Time Zone Alaska Time Zone The Alaska Time Zone observes standard time by subtracting nine hours from Coordinated Universal Time (). During daylight saving time its time offset is eight hours (). The clock time in this zone is based on mean solar time at the 135th meridian west of the Greenwich Observatory. The zone includes nearly all of the U.S. state of Alaska and is one hour behind the Pacific Time Zone. The western Aleutian Islands observe Hawaii–Aleutian Time, one hour behind the remainder of the state. Effective from 2007, the local time changes from AKST to AKDT at 02:00 LST
Aleutian Range Aleutian Range The Aleutian Range is a major mountain range located in southwest Alaska. It extends from Chakachamna Lake (80 miles/130 km southwest of Anchorage) to Unimak Island, which is at the tip of the Alaska Peninsula. It includes all of the mountains of the Peninsula. The Aleutian Range is special because of its large number of active volcanoes, which are also part of the larger Aleutian Arc. The mainland part of the range is about 600 miles (1000 km) long. The Aleutian Islands are (geologically) a partially submerged western extension of the range that stretches for another 1,600 km
