About UTC and PST
Coordinated Universal Time (UTC, UTC+0) covers the global reference used in aviation, computing and science, and never changes for daylight saving. Pacific Time (PST, UTC−8) covers Los Angeles, San Francisco, Seattle and Vancouver, and observes daylight saving (PST in winter, PDT 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.
