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 India Standard Time (IST)
India Standard Time (IST, IANA: Asia/Kolkata) is the civil time of the Republic of India and Sri Lanka, set at UTC+5:30 — one of the world's most populous 30-minute-offset time zones. India does not observe Daylight Saving Time per the Government of India directive (a brief DST trial in 1942-1945 during WWII was discontinued; subsequent proposals from 2010-2017 were rejected by the Indian Government citing minimal energy savings + agricultural sector disruption). IST is defined as the local mean solar time at 82.5°E longitude (passing through Shankargarh fort in Uttar Pradesh, with the reference clock at the National Physical Laboratory in New Delhi per the Indian Institute of Astrophysics). The 30-minute offset is preserved because India's east-west extent (68°E to 97°E) spans ~28° of longitude — approximately 2 hours of solar time — and the central meridian is most representative for a single unified zone. IST serves approximately 1.4 billion people in India + 22 million in Sri Lanka (Sri Lanka observes SLST = UTC+5:30, identical to IST). Major cities: Mumbai (12.5M), Delhi (16.8M, NCR 29M), Bengaluru (8.4M), Hyderabad (10M), Chennai (7M), Kolkata (4.5M), Ahmedabad (5.5M), Pune (3.1M). Affects: BSE/NSE stock exchanges, IPL Indian Premier League cricket schedules.
