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 Singapore Time (SGT)
Singapore Time (SGT, IANA: Asia/Singapore) is the civil time of the Republic of Singapore, set at UTC+8:00 year-round (no DST). Singapore historically used UTC+7:30 (with Malaya) before 1982, then adjusted to UTC+8:00 in January 1982 to align with major regional trading partners China + Hong Kong + Malaysia. The Singapore Public Utilities Board oversees official timekeeping per the legal-time reference at the National University of Singapore. SGT is identical in offset to China Standard Time (CST), Malaysia Time (MYT), Hong Kong Time (HKT), Philippine Time (PHT), Western Australia Time (AWST), Brunei Time (BNT) — making coordination across the Asia-Pacific tropics seamless. SGT serves the city-state of Singapore's approximately 5.9 million residents (citizens + permanent residents + foreign workers). Despite its small geographic size (728 km² — smaller than New York City's 5 boroughs), Singapore is one of Asia's most important financial centers. Affects: SGX (Singapore Exchange) trading hours 09:00-17:00 SGT, Port of Singapore Authority shipping operations (the world's second-busiest container port after Shanghai), Changi Airport flight scheduling (often the world's #1-ranked airport), and the Marina Bay Sands hotel + Gardens by the Bay operating hours.
