About Atlantic Standard Time (AST)
Atlantic Standard Time (AST, IANA: America/Halifax, America/Puerto_Rico) is the time zone for the Canadian Maritime provinces and most of the Caribbean, set at UTC-4:00. AST is observed in: Nova Scotia, New Brunswick, Prince Edward Island, Labrador (partially), Newfoundland's Labrador portion, eastern Quebec, Puerto Rico, US Virgin Islands, Bermuda, Anguilla, Antigua, Aruba, Barbados, British Virgin Islands, Curaçao, Dominica, Grenada, Guadeloupe, Martinique, Saint Lucia, Saint Vincent, Trinidad and Tobago, and Venezuela (since 2007). Canadian Maritime provinces observe AST in winter and switch to ADT = UTC-3:00 in summer per the Energy Policy Act-aligned Canadian schedule. The Caribbean territories (Puerto Rico, USVI, Bermuda) and US territories observe AST year-round without DST per their territorial governments. AST is the same offset as EDT (Eastern Daylight Time) during US summer months, so Halifax and New York are on the same clock in summer but Halifax is one hour ahead in winter.
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.
