We recommend looking up by location name, not time zone name.

Time zone offset: UTC - 10 hours

HAST is 10 hours behind of Coordinated Universal Time (UTC)

Note that some places observe daylight saving time/summer time during summer, and are therefore using HADT instead in the summer. See below for details.

Time zone abbreviation: HAST

Full name is Hawaii-Aleutian Standard Time

Email time zone indicator: -1000

An email sent from someone in the HAST time zone will have the time zone listed as "-1000" in the headers of the email. (However, "-1000" does not have to be in HAST, as other time zones could have the same UTC offset).

For actual dates DST might be observed, look at the examples below
