About the time in San Antonio
The zone identifier America/Monterrey is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Monterrey keeps pointing at Monterrey time whatever the date, which is why every timestamp on this page is built from it.
San Antonio sits at latitude 22.70, in the tropical band, so day length here swings only a little between midwinter and midsummer — today's 12h 42m is one point on that curve, not a fixed value.
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.
