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 Central Africa Time (CAT)
Central Africa Time (CAT, IANA: Africa/Johannesburg, Africa/Harare) is the civil time for Central and Southern African countries, set at UTC+2:00 year-round (no DST). CAT serves approximately 200 million people across: Botswana, Burundi, DR Congo (eastern half), Egypt (since 2014 reverting from earlier DST trial; year-round UTC+2), eSwatini (Swaziland), Lesotho, Libya, Malawi, Mozambique, Namibia (since 2017 reverting from earlier WAT trial; year-round UTC+2), Rwanda, South Africa, Sudan (UTC+2 since 2017), Zambia, Zimbabwe. CAT shares the same UTC offset as Eastern European Time (EET) in winter, Egypt Standard Time (EET-Egypt), and Israel Standard Time (IST). Major CAT cities: Johannesburg (5.6M city, 10M metro — economic capital of Sub-Saharan Africa), Cape Town (4.7M metro), Cairo (10M city, 22M metro — the largest city in Africa and the Middle East), Khartoum (5.3M), Lusaka (2.7M), Harare (1.6M), Tripoli (1.2M), Pretoria (740K). Affects: JSE Johannesburg Stock Exchange trading, Cairo + Alexandria Stock Exchange (EGX) trading hours, Kruger National Park safari schedules.
