PST: Pacific Time
--:--:--
BST is 8 hours ahead of PST all year.
Both clocks change for daylight saving on similar schedules, so the gap between them does not move.
PST also abbreviates Philippine Standard Time (UTC+8). These pages use the North American meaning.
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) do not overlap: daytime in Pacific Time falls outside the working day in British Time, so one side needs an early morning or late evening.
Offsets are computed from the IANA time zone database for January 15 and July 15 of the current year. PST here means Pacific Time (United States and Canada); BST means British Time (United Kingdom).
