What is AST in AKST?
Alaska Time is 5 hours behind
Atlantic Time is on UTC−3:00 and Alaska Time is on UTC−8:00 right now. Both are on daylight saving, so their clocks read ADT and AKDT. That gap holds all year, because both zones change their clocks together.

Scheduling between the two
Working hours overlap from 2:00 pm to 6:00 pm ADT, which is 9:00 am to 1:00 pm AKDT. Anything inside that window falls in the normal working day at both ends.
A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.
Atlantic Time (ADT) is used in Nova Scotia, New Brunswick and Puerto Rico
