Photo credit: Â© Schoolgirl | Dreamstime.com. Enjoying your time spent in Barbados will prove much easier once you adjust to the time difference on local clocks. Barbados is in the Atlantic time zone, which is four hours behind Greenwich Mean Time. It is one hour ahead of Eastern Standard Time; however, the island does not observe daylight-saving time. This means that from April to October, the Eastern time in America is the same as the time in Barbados. From October to April, the East Coast of the United States is one hour behind Barbados.
