PST: Pacific Time
--:--:--
CST is 2 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.
CST also abbreviates China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). These pages use the North American meaning.
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.
