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.
About Philippine Time (PHT)
Philippine Time (PHT, IANA: Asia/Manila) — also called Philippine Standard Time (PST) — is the civil time of the Republic of the Philippines, set at UTC+8:00 year-round (no DST). Philippines observed Daylight Saving Time briefly between 1936-1938 and 1942-1944 during Japanese occupation, but has remained on PHT year-round since 1944. The Philippine Standard Time Act of 2013 (Republic Act 10535) established PHILMET — the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) — as the official timekeeper, and mandated that all government clocks display synchronized PHT. PHT is identical in offset to China Standard Time (CST), Hong Kong Time (HKT), Singapore Time (SGT), Malaysia Time (MYT), Brunei Time (BNT), Australian Western Standard Time (AWST). PHT serves approximately 117 million Filipino people across 7,641 islands organized into 17 regions + 81 provinces. Major Philippine cities: Manila + NCR (1.8M city, 13.5M metro — National Capital Region also called Metro Manila is the world's most densely populated metropolitan area), Quezon City (3M — NCR), Caloocan (1.7M — NCR), Davao (1.8M — Mindanao), Cebu (1M — Visayas), Zamboanga (980K). Affects: PSE (Philippine Stock Exchange) trading hours, BPO (Business Process Outsourcing) industry shift schedules.
