About the time in San Antonio
Clocks in San Antonio stay put all year. There is no summer-time switch to remember, so UTC −6 is what you will get in January and in July alike — useful if you book recurring calls with people in Mexico.
San Antonio runs on America/Monterrey, 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.
