About China Standard Time (CST)
China Standard Time (CST, IANA: Asia/Shanghai) is the unified civil time of the People's Republic of China, set at UTC+8:00 year-round (no DST). Despite China's vast east-west extent (~5,200 km from Xinjiang's western border at 73°E to Heilongjiang's eastern border at 135°E — 62° of longitude or ~4 hours of solar time), the entire country uses a single time zone since 1949 (consolidated from 5 separate zones used during the Republic of China era). This means Kashgar Xinjiang sees solar noon at approximately 14:00 CST in summer, while Shanghai sees solar noon at approximately 11:50 CST — a stark practical discrepancy. Hong Kong Time (HKT) and Macau Time (MOT) are identical at UTC+8 but use different IANA identifiers for historical reasons. CST serves approximately 1.42 billion people. CST is identical in offset to Singapore Time (SGT), Malaysia Time (MYT), Philippine Time (PHT), Australian Western Standard Time (AWST), Hong Kong Time (HKT). Major CST cities: Shanghai (24M), Beijing (21.5M), Chongqing (32M), Guangzhou (15M), Shenzhen (12.5M), Chengdu (16.3M), Tianjin (13.7M), Wuhan (11M), Xi'an (13M), Hangzhou (11.9M). Affects: SSE + SZSE stock exchanges, Beijing Central Government working 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.
