Daylight saving and how the gap changes

CT is 6 hours behind BST for most of the year. British Summer Time and Central Time (US) both observe daylight saving, but they change their clocks on different dates, so for a short period each spring and each autumn the gap differs by an hour — the converter above always reflects the correct offset for the date you pick.
