About the time in San Francisco
Sunrise today lands at 05:27 and sunset at 05:50 local time, giving 12h 23m of daylight. Those figures come from the city's own coordinates (9.99, -84.13) rather than a country-wide average, so they match what you would actually see from a window in San Francisco.
San Francisco runs on America/Costa_Rica, which puts the city UTC −6 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
The zone identifier America/Costa_Rica is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Costa_Rica keeps pointing at Costa Rica time whatever the date, which is why every timestamp on this page is built from it.
