About PST and GMT
Pacific Time (PST, UTC−8) covers Los Angeles, San Francisco, Seattle and Vancouver, and observes daylight saving (PST in winter, PDT in summer). Greenwich Mean Time (GMT, UTC+0) covers London in winter, Reykjavik and Accra, and fixed at UTC+0 (the UK switches to BST, UTC+1, in summer).
Because Pacific Time observes daylight saving while the other side doesn't, the difference shifts by one hour between winter and summer — the table below shows both.
