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 Alaska Standard Time (AKST)
Alaska Standard Time (AKST, IANA: America/Anchorage and America/Juneau) is the time zone for most of the State of Alaska, set at UTC-9:00. AKST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966 + Energy Policy Act of 2005; Alaska switches to Alaska Daylight Time (AKDT = UTC-8:00) for the remainder of the year. The vast Alaska time zone covers ~3,200 km east-to-west — from Ketchikan to Atka in the Aleutians — and is the only US time zone that spans more than 1,000 miles longitudinally, meaning solar-noon in different Alaska cities varies by over an hour from local clock time. Major population centers: Anchorage (~290,000), Fairbanks (~95,000), Juneau state capital (~32,000). Used in coordination of cruise-ship schedules through the Inside Passage, North Slope oil-pipeline operations, US Air Force JBER and Eielson AFB activities, and Alaska commercial fishing season openings managed by ADF&G.
