AZOT is not heavily split in the current catalog, but the short label still hides the underlying IANA zone and any future policy change. The safe pattern is to write the abbreviation for humans and the zone for machines.
Atlantic/Azores has an upcoming offset change on October 25, 2026. After that point, AZOT on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation.
For precise work, the safest equivalent of AZOT is the exact IANA zone used by your city or system. Atlantic/Azores sits on UTC at the moment, which keeps date math simple, but seasonal rules and government changes still apply.
Within this single zone (Atlantic/Azores, +00:00), AZOT is unambiguous, so the abbreviation and the IANA zone effectively interchange.
