About the time in San Mateo
Sunrise today lands at 06:33 and sunset at 07:50 local time, giving 13h 18m of daylight. Those figures come from the city's own coordinates (37.56, -122.35) rather than a country-wide average, so they match what you would actually see from a window in San Mateo.
San Mateo follows the civil time used across its region of United States; there is no separate local reckoning inside the city.
If you are coordinating from another country, the shortcut is the working window: a normal San Mateo day of 09:00–17:00 falls between 16:00–00:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
