GMT/BST
GMT (Greenwich Mean Time, UTC+0) is in effect in the United Kingdom in the winter, and BST (British Summer Time, UTC+1) between late March and October. This seasonal change is tailored in such a way that it gives more daylight time span so that the timepieces advance one hour during the spring and revert once more during the fall.

Most of the Caribbean islands remain on AST throughout the year, but Canadian provinces such as Nova Scotia and New Brunswick change to Atlantic Daylight Time (ADT, UTC-3) in summer.
