AST and ADT time converter

AST uses UTC-04:00. ADT uses UTC-03:00.

Daylight saving note: this abbreviation page uses the offset for the abbreviation in the URL. Standard and daylight variants are separate pages, such as PST/PDT or EST/EDT. City-level pages need IANA time zones such as America/Los_Angeles to switch automatically.
