DST
Barbados in the western Atlantic no longer observes Daylight Saving Time, like many Caribbean nations. The last observance of the DST related time clock adjustment was between Sunday, 20 April 1980 at 2:00 AM – Thursday, 25 September 1980 at 2:00 AM. On 25 September of that year the clock was shifted from -3:00 –> -4:00 where it has remained since.
