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.
The zone identifier America/Mexico_City is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Mexico_City keeps pointing at Mexico City time whatever the date, which is why every timestamp on this page is built from it.
