About Japan Standard Time (JST)
Japan Standard Time (JST, IANA: Asia/Tokyo) is the civil time of Japan, set at UTC+9:00 year-round (no DST). Japan observed Daylight Saving Time only briefly during American Occupation (1948-1951) and discontinued it after the Treaty of San Francisco. JST is also called Nippon Hyōjunji (日本標準時) and is officially maintained by the National Institute of Information and Communications Technology (NICT) — Japan operates a sophisticated atomic-clock-based timekeeping system at NICT Koganei facility with caesium beam frequency standards CSF-2 + Sr-87 optical lattice clock. JST is identical in offset to Korea Standard Time (KST), Yakutsk Time (Russian Far East), Western Indonesian Time WIT (eastern Indonesia), and Palau Time (PWT). JST serves Japan's approximately 125 million residents across 47 prefectures. Major JST cities: Tokyo (14M city, 37M metro — the world's largest metropolitan area by population), Yokohama (3.8M — Tokyo bay metro), Osaka (2.7M, Kansai region 19M metro), Nagoya (2.3M, Chukyo region 9.5M metro), Sapporo (1.9M — Hokkaido capital), Fukuoka (1.6M — Kyushu hub), Kobe (1.5M), Kawasaki (1.5M), Saitama (1.3M). Affects: TSE (Tokyo Stock Exchange) trading hours 09:00-15:00 JST, Tokyo Sumo Grand Tournaments, Shinkansen bullet-train scheduling, Tokyo Disney + USJ park operating hours.
About Singapore Time (SGT)
Singapore Time (SGT, IANA: Asia/Singapore) is the civil time of the Republic of Singapore, set at UTC+8:00 year-round (no DST). Singapore historically used UTC+7:30 (with Malaya) before 1982, then adjusted to UTC+8:00 in January 1982 to align with major regional trading partners China + Hong Kong + Malaysia. The Singapore Public Utilities Board oversees official timekeeping per the legal-time reference at the National University of Singapore. SGT is identical in offset to China Standard Time (CST), Malaysia Time (MYT), Hong Kong Time (HKT), Philippine Time (PHT), Western Australia Time (AWST), Brunei Time (BNT) — making coordination across the Asia-Pacific tropics seamless. SGT serves the city-state of Singapore's approximately 5.9 million residents (citizens + permanent residents + foreign workers). Despite its small geographic size (728 km² — smaller than New York City's 5 boroughs), Singapore is one of Asia's most important financial centers. Affects: SGX (Singapore Exchange) trading hours 09:00-17:00 SGT, Port of Singapore Authority shipping operations (the world's second-busiest container port after Shanghai), Changi Airport flight scheduling (often the world's #1-ranked airport), and the Marina Bay Sands hotel + Gardens by the Bay operating hours.
