Sunrise today lands at 06:35 and sunset at 07:15 local time, giving 12h 40m of daylight. Those figures come from the city's own coordinates (20.44, -103.24) rather than a country-wide average, so they match what you would actually see from a window in San Mateo.
San Mateo runs on America/Mexico_City, 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.
Clocks in San Mateo stay put all year. There is no summer-time switch to remember, so UTC −6 is what you will get in January and in July alike — useful if you book recurring calls with people in Mexico.
