About the time in San Mateo
San Mateo sits at latitude 0.85, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 08m is one point on that curve, not a fixed value.
Sunrise today lands at 06:17 and sunset at 06:25 local time, giving 12h 08m of daylight. Those figures come from the city's own coordinates (0.85, -79.62) rather than a country-wide average, so they match what you would actually see from a window in San Mateo.
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 14:00–22:00 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.
