About time in San Antonio
San Antonio is the seat of Bexar County and the westernmost of Texas's four largest cities, yet it remains well inside the Central zone — driving I-10 toward the west, clocks only change at the Hudspeth County line roughly 450 miles away, where the state's small Mountain Time pocket begins.
Because it lies about three degrees of longitude west of Houston while sharing the same zone, San Antonio's sunrises and sunsets run around twelve minutes later than Houston's even though both cities' clocks read identically.
Joint Base San Antonio — combining Lackland, Randolph, and Fort Sam Houston — schedules basic-training graduations and flight operations on the same Central clock as the city, alongside the military's standard 24-hour notation.
