how to abbreviate alaska time
See full time zone map. Some places observe daylight saving time/summer time during the summer, and therefore use AKDT (Alaska Daylight Time) in the summer. An email sent from someone in the Alaska Standard Time (AKST) time zone will have the time zone listed as -0900 in the headers of the email. (However, -0900 does not have to be in Alaska Standard Time, as other time zones could have the same UTC offset).
