AST covers 31 IANA time zones, including America/Anguilla, America/Antigua, America/Aruba, America/Barbados, America/Blanc-Sablon, America/Curacao and 25 more. Daylight saving is applied automatically for whichever zone a city actually uses, so the result stays correct across the changeover.
The standard time observed in parts of eastern Canada (e.g., Nova Scotia, New Brunswick during winter), some Caribbean islands (e.g., Puerto Rico, US Virgin Islands year-round), and parts of South America. Some regions observing AST switch to ADT for daylight saving.
