About the time in San Mateo
San Mateo runs on America/Merida, 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.
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 15:00–23:00 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.
Sunrise today lands at 05:37 and sunset at 06:17 local time, giving 12h 40m of daylight. Those figures come from the city's own coordinates (20.11, -88.72) rather than a country-wide average, so they match what you would actually see from a window in San Mateo.
