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 Gulf Standard Time (GST)

The 'Gulf Standard Time' specifically refers to UAE + Oman in regional aviation/business usage. GST shares the same UTC offset as Mauritius Time (MUT), Armenia Time (AMT), Azerbaijan Time (AZT), Georgia Time (GET), and is +1 hour ahead of Moscow / Saudi Arabia. Major GST cities: Dubai (3.5M city, 4.8M metro — UAE + global trade hub), Abu Dhabi (1.5M city, 2.9M metro — UAE capital), Sharjah (1.7M), Muscat Oman (1.7M metro — capital), Salalah Oman (370K), Baku Azerbaijan (2.3M), Yerevan Armenia (1.1M), Tbilisi Georgia (1.2M).
