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 Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST, IANA: Australia/Sydney) is the civil time of Australia's most populous eastern states — New South Wales (NSW), Victoria (VIC), Queensland (QLD), Tasmania (TAS), Australian Capital Territory (ACT) — set at UTC+10:00. AEST is observed in winter; NSW + VIC + TAS + ACT switch to Australian Eastern Daylight Time (AEDT = UTC+11) from the first Sunday of October to the first Sunday of April. Queensland does NOT observe DST (stays on AEST year-round) — a state-level decision affirmed by referendums in 1992. AEST serves approximately 21 million Australians — about 80% of the country's population. AEST is identical in offset to Vladivostok Time (Russia), Papua New Guinea Time (PGT), Guam-Chamorro Time (CHST), and the US-territory Northern Mariana Islands. Major AEST cities: Sydney NSW (5.4M metro — largest Australian city + ASX home), Melbourne VIC (5.1M metro — 2nd-largest), Brisbane QLD (2.6M metro — 3rd-largest, on AEST year-round), Gold Coast QLD (725K — tourist coastline), Newcastle NSW (475K), Canberra ACT (450K — federal capital), Hobart TAS (250K — Tasmanian capital). Affects: ASX trading hours 10:00-16:00 AEST, Australian Cricket / AFL game scheduling, Great Barrier Reef + Sydney Opera House tourism operating hours.
