What AKST and ART Actually Are
AKST — Alaska Standard Time
Anchorage, Fairbanks, Juneau. Standing at UTC-9:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to AKST.
Alaska compressed four time zones into one in 1983, moving most of the state onto a single clock to keep business hours aligned with the rest of the country.
ART — Argentina Time
Buenos Aires, Córdoba, Rosario. Standing at UTC-3:00 as written, and the region does not change its clocks, so that offset holds all year. Argentina does not observe daylight saving, so this offset is fixed year-round.
Argentina has changed its time zone rules more than a dozen times since 1930 and abandoned daylight saving in 2009.
What This Means in Practice
This gap is not fixed
AKST changes its clocks and ART does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
