About New Zealand Standard Time (NZST)
New Zealand Standard Time (NZST, IANA: Pacific/Auckland) is the civil time of New Zealand mainland (North Island + South Island), set at UTC+12:00. NZST is observed in winter; New Zealand switches to New Zealand Daylight Time (NZDT = UTC+13) from the last Sunday of September to the first Sunday of April per the Time Act of 1974 + Standard Time Act of 2007 (a slightly different DST schedule than Australia + most of the Northern Hemisphere). The Chatham Islands archipelago (Chatham, Pitt Islands — 800 km east of NZ mainland) uses Chatham Standard Time (CHAST = UTC+12:45) and Chatham Daylight Time (CHADT = UTC+13:45) — one of the world's only 45-minute-offset zones along with Nepal UTC+5:45 and Eucla WA UTC+8:45. NZST serves approximately 5.2 million New Zealanders. NZST is identical in offset to Fiji Time (FJT), Marshall Islands Time, Tuvalu Time, Wallis and Futuna Time. Major NZST cities: Auckland (1.7M metro — North Island), Wellington (210K city, 425K metro — capital), Christchurch (380K — South Island), Hamilton (180K), Tauranga (155K), Dunedin (135K), Queenstown (25K — tourist hub + Lord of the Rings filming locations). Affects: NZX (New Zealand Stock Exchange) trading hours, All Blacks rugby match scheduling, Hobbiton + Milford Sound tourism operating hours.
About Greenwich Mean Time (GMT)
Greenwich Mean Time (GMT, IANA: Europe/London) is the historic and current civil time of the United Kingdom (during winter), Ireland (during winter), Portugal mainland (during winter), Iceland (year-round), and most West African countries. GMT is set at UTC+0 — the time on the Prime Meridian (0° longitude) running through the Royal Observatory in Greenwich, southeast London. Established as the global time reference by the 1884 International Meridian Conference in Washington DC, GMT served as the world's primary civil-time reference from 1884 until 1972 when UTC (Coordinated Universal Time) was adopted as the new precision standard. The UK switches from GMT to British Summer Time (BST = UTC+1) at 01:00 GMT on the last Sunday of March and back to GMT at 02:00 BST on the last Sunday of October per EU Directive 2000/84/EC (UK retained this schedule after Brexit). GMT affects: London Stock Exchange (LSE) trading hours, BBC World Service broadcast time-stamps, all aviation NOTAMs and weather METARs which use UTC = GMT, and ICAO + IMO worldwide maritime/aviation coordination.
