GMT-2 reads cleanly across the Americas in this dataset, but the same letters can mean different things elsewhere (notably CST, EST, and IST overlap with non-American labels). Pin the IANA zone when the audience is international.
America/Nuuk has an upcoming offset change on October 24, 2026. After that point, GMT-2 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 GMT-2 is the exact IANA zone used by your city or system. America/Nuuk sits at -01:00, behind UTC, which means daily logs in this zone reach a new calendar date after UTC does — relevant for date-aligned reports and billing cutoffs.
Within this single zone (America/Nuuk, -01:00), GMT-2 is unambiguous, so the abbreviation and the IANA zone effectively interchange.
