About the time in San Antonio
San Antonio sits at latitude 18.78, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 38m is one point on that curve, not a fixed value.
San Antonio 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.
If you are coordinating from another country, the shortcut is the working window: a normal San Antonio 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.
