BST: British Time
--:--:--
CET is 1 hour ahead of BST all year.
Both clocks change for daylight saving on similar schedules, so the gap between them does not move.
The United Kingdom uses GMT in winter and BST (British Summer Time) in summer. BST also abbreviates Bangladesh Standard Time (UTC+6).
One instant, two local clocks
Both lanes show the same instant. Local dates, daylight, and offsets come from each IANA zone on the selected date, so daylight saving changes are included.

Standard business hours (9:00 AM to 5:00 PM) overlap from 9:00 AM to 4:00 PM in BST, which is 10:00 AM to 5:00 PM in CET.
Offsets are computed from the IANA time zone database for January 15 and July 15 of the current year. BST here means British Time (United Kingdom); CET means Central European Time (most of continental Europe).
