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.
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.
