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.
About Hong Kong Time (HKT)
Hong Kong Time (HKT, IANA: Asia/Hong_Kong) is the civil time of the Hong Kong Special Administrative Region of the People's Republic of China, set at UTC+8:00 year-round (no DST). Hong Kong observed Daylight Saving Time intermittently between 1941-1979 but discontinued the practice in 1979 to better align with regional trading partners. HKT is identical in offset to China Standard Time (CST), Macau Time (MOT), Singapore Time (SGT), Philippine Time (PHT), Australian Western Standard Time (AWST), Malaysia Time (MYT). HKT serves Hong Kong's approximately 7.4 million residents in one of the world's most densely populated and economically dynamic territories (Hong Kong Island, Kowloon, New Territories, Lantau Island, and 263 outlying islands). Major Hong Kong districts: Central + Western (financial district), Wan Chai, Causeway Bay, Tsim Sha Tsui, Mong Kok, Sha Tin, Tuen Mun. Despite Hong Kong's small geographic size (1,114 km²), it is the world's 4th-largest financial center after New York, London, Singapore per Z/Yen GFCI rankings. Affects: HKEX (Hong Kong Stock Exchange) trading hours 09:30-16:00 HKT, Hong Kong International Airport at Chek Lap Kok flight operations, MTR + Star Ferry public transit schedules, and Hong Kong horse-racing at Happy Valley + Sha Tin race-courses.
