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 Indochina Time (ICT)
Indochina Time (ICT, IANA: Asia/Bangkok, Asia/Ho_Chi_Minh) is the civil time of mainland Southeast Asia (excluding Myanmar + Indonesia), set at UTC+7:00 year-round (no DST). ICT serves approximately 250 million people across: Thailand, Vietnam, Cambodia, Laos, Christmas Island (Australian territory in Indian Ocean), Java + Sumatra + western Indonesia (which uses Western Indonesian Time WIB = identical UTC+7 offset). ICT shares its offset with Krasnoyarsk Time (Russia, UTC+7) and Davis Antarctica research station. Major ICT cities: Bangkok Thailand (10.7M metro — Southeast Asia's largest tourist destination + ASEAN economic hub), Ho Chi Minh City Vietnam (10M city, 14M metro — formerly Saigon, Vietnam's largest city), Hanoi Vietnam (8M metro — capital), Jakarta Indonesia (10.5M city, 35M metro — uses WIB which is identical to ICT but a different zone-name), Phnom Penh Cambodia (2M), Vientiane Laos (820K). Affects: SET (Stock Exchange of Thailand) trading hours, HOSE + HNX (Vietnam stock exchanges) trading, Phnom Penh Securities Exchange (CSX) hours, Bangkok BTS Skytrain + MRT subway operating hours, and ASEAN diplomatic-meeting schedules.
