About Pacific Standard Time (PST)
Pacific Standard Time (PST, IANA: America/Los_Angeles) is the standard time zone for the US West Coast and Canadian westernmost provinces, set at UTC-8:00. PST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966; the region switches to Pacific Daylight Time (PDT = UTC-7:00) the rest of the year. PST is used by ~50 million people in California, Oregon, Washington, Nevada (most), British Columbia, Yukon Territory, and the Mexican states of Baja California Norte. Major cities: Los Angeles, San Francisco, San Diego, Seattle, Portland, Sacramento, Las Vegas, Vancouver BC. PST is the time zone of US tech hubs (Silicon Valley, Seattle, Vancouver) — global software-release coordination, Big-Tech corporate-earnings calls, Hollywood production schedules, and NYSE/Nasdaq market hours (PST 06:30-13:00) all reference PST/PDT. Mexico abolished DST nationwide in 2022 except for border zones, complicating Baja conversions.
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.
