Most of Alaska is in the Alaskan Time Zone but a portion of the Aleutian Islands are in the Hawaii-Aleutian Time Zone. Alaskan time is one time zone west (behind) Pacific Time. Hawaii is two time zones west of Pacific Time (however, Hawaii does not use Daylight Saving Time so during Daylight Saving Time, it is three hours behind Pacific Time.
Arizona, while it is in the Mountain Time Zone, also does not utilize Daylight Saving Time. The portions of Indiana in the Eastern Time Zone previously did not observe Daylight Saving Time. Visit the What time is it in Indiana? site for more information about Indiana's interesting time zone history.
