About Plymouth time
Plymouth keeps one clock.
Plymouth, the designated capital of Montserrat, sits in the Atlantic Standard Time zone on a time that keeps you one hour ahead of Eastern Standard Time and in sync with much of the Caribbean. Despite the city being largely abandoned after volcanic eruptions, the operational government and nearby communities maintain a Caribbean pace: daylight hours are steady year-round, making coordination with the Americas seamless thanks to the constant four-hour lag behind UTC.
