About Coordinated Universal Time (UTC)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, defined since 1972 as the time at the Prime Meridian (0° longitude) maintained by BIPM (Bureau International des Poids et Mesures) in Sèvres, France. UTC is computed as a weighted average of approximately 400 atomic clocks at ~80 national metrology institutes (NIST in the US, NPL in UK, PTB in Germany, NICT in Japan, KRISS in Korea, etc.) per the formal definition in ITU-R Recommendation TF.460-6 (2002). UTC is functionally identical to GMT (Greenwich Mean Time) for civil purposes but differs slightly in its underlying timescale — UTC uses atomic seconds with occasional leap seconds inserted (announced by IERS Bulletin C ~6 months in advance, last leap second was December 31, 2016, and the system may be retired by 2035 per Resolution D of CGPM 2022). UTC is the standard for aviation (ICAO Annex 5), maritime navigation (IMO COLREGS), all internet protocols (NTP, PTP per IEEE 1588), all scientific publications, GPS / Galileo / GLONASS / BeiDou GNSS, and Universal Time on Wikipedia/Wikidata.
About Alaska Standard Time (AKST)
Alaska Standard Time (AKST, IANA: America/Anchorage and America/Juneau) is the time zone for most of the State of Alaska, set at UTC-9:00. AKST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966 + Energy Policy Act of 2005; Alaska switches to Alaska Daylight Time (AKDT = UTC-8:00) for the remainder of the year. The vast Alaska time zone covers ~3,200 km east-to-west — from Ketchikan to Atka in the Aleutians — and is the only US time zone that spans more than 1,000 miles longitudinally, meaning solar-noon in different Alaska cities varies by over an hour from local clock time. Major population centers: Anchorage (~290,000), Fairbanks (~95,000), Juneau state capital (~32,000). Used in coordination of cruise-ship schedules through the Inside Passage, North Slope oil-pipeline operations, US Air Force JBER and Eielson AFB activities, and Alaska commercial fishing season openings managed by ADF&G.
