BST (British Summer Time) and GMT (Greenwich Mean Time) differ in their application and time periods. BST is used in the UK during the summer months to make better use of daylight, moving the clocks forward one hour from GMT. GMT, however, remains constant throughout the year, serving as the baseline time zone from which others are calculated. Hence, BST is essentially GMT+1 during the summer.
