About Colombia Time (COT)
Colombia Time (COT, IANA: America/Bogota) is the official civil time of the Republic of Colombia, set at UTC-5:00 year-round. Colombia abolished Daylight Saving Time in 1993 after a brief experimental DST period (1992-1993), so COT is observed without seasonal change since then. COT serves approximately 52 million people across Colombia's 32 departments + Bogotá Capital District. Major cities: Bogotá (8M city, 11M metro — capital), Medellín (2.5M city, 4M metro), Cali (2.3M), Barranquilla (1.3M), Cartagena (1M), Cúcuta (700K), Bucaramanga (600K). COT is identical in offset to Eastern Standard Time (EST) US, Cuban Standard Time (CST-Cu), Peru Time (PET), and Ecuador Time (ECT). The San Andrés and Providencia archipelago in the Caribbean Sea (closer to Nicaragua than to mainland Colombia) also observes COT. Affects: Bolsa de Valores de Colombia (BVC) trading hours, Ecopetrol oil-pipeline operations, Café de Colombia harvest-season coordination, and Cartagena de Indias cruise-ship port arrivals scheduling.
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.
