Ha why “Azores time zone” including Ireland and Iceland when the Azores are miles away. “Atlantic time zone” seems to make more sense.

In the Americas, "Atlantic time zone" refers to the time zone 1 hour before Eastern. Presumably Azores time is meant to avoid confusion with existing Atlantic time.

Also, Azores Time Zone is the existing name of the time zone.
