UTC−2. (BRT+1) UTC−04:00 is an identifier for a time offset from UTC of −04:00. It is observed in the Eastern Time Zone (e.g., in Canada and the United States) during the warm months of daylight saving time, as Eastern Daylight Time. The Atlantic Time Zone observes it during standard time (cold months). It is observed all year in the ...
Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time (UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour gap.

This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00). It includes countries and regions that observe them during standard time or year-round. The main purpose of this page is to list the current standard time offsets ...
The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time ( AST )—by subtracting four hours from Coordinated Universal Time ( UTC ), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight ...

Each time zone is defined by a standard offset from Coordinated Universal Time (UTC). The offsets range from UTC−12:00 to UTC+14:00, and are usually a whole number of hours, but a few zones are offset by an additional 30 or 45 minutes, such as in India and Nepal.
