About Hawaii Standard Time (HST)
Hawaii Standard Time (HST, IANA: Pacific/Honolulu) is the time zone for the State of Hawaii and the Aleutian Islands of Alaska west of 169.5°W. HST is UTC-10:00 year-round and does not observe Daylight Saving Time per Hawaii Revised Statutes §1-31 (Hawaii opted out of the Uniform Time Act of 1966). When the US mainland switches to Daylight Saving Time in March, the offset from Hawaii to the West Coast (Pacific Time) becomes 3 hours instead of the standard 2 hours. Honolulu sees solar noon at approximately 12:30 PM HST in summer. HST is the same offset as Cook Island Time (CKT) and Tahiti Time (TAHT) in French Polynesia, allowing easy mental conversion across the central Pacific. Time-sensitive activities affected by HST include Pacific tsunami warning system coordination per NOAA NTWC, US military operations from Joint Base Pearl Harbor-Hickam, and the Mauna Kea astronomical observatories' nightly observing schedules.
About West Africa Time (WAT)
West Africa Time (WAT, IANA: Africa/Lagos, Africa/Kinshasa) is the civil time for West African and Central African countries, set at UTC+1:00 year-round (no DST). WAT serves approximately 350 million people across: Algeria, Angola, Benin, Cameroon, Central African Republic, Chad, DR Congo (western half), Republic of Congo, Equatorial Guinea, Gabon, Niger, Nigeria, São Tomé and Príncipe, Tunisia. WAT is the same offset as Central European Time (CET) in winter, easing African business coordination with Western European partners. Major WAT cities: Lagos Nigeria (15M metro — the largest city in Africa and home to one of the world's fastest-growing populations), Kinshasa DRC (17M metro), Algiers (3.7M metro), Tunis (2.4M metro), Yaoundé (2.8M), Douala (2.7M), Brazzaville (1.8M), Luanda (8M metro), N'Djamena (1.4M). The eastern half of the DRC uses Central Africa Time (CAT = UTC+2). Affects: Nollywood film-industry production in Lagos, African Union meetings, Lagos NGX (Nigerian Exchange Group) trading hours, and Lagos-São Paulo + Lagos-Buenos Aires Atlantic-shipping schedules.
