ACS Atlas Discontinuation Notice
The Terran Atlas time zone and location database with 13+ million records has replaced the ACS Atlas in Delphic Oracle and Timaeus due to technological (no native Mac version of the ACS Atlas at the present time) and legal issues. The original maintainer of the ACS Atlas (Astro Communication Services) filed bankruptcy. Then Astrolabe bought the Atlas and sued the Olson Time Zone database which was dismissed with prejudice after EFF took up the case.
