Central Time (CT) · CST (UTC−6) in winter · CDT (UTC−5) during Daylight Saving Time · El Paso uses Mountain Time
Most of Texas is on Central Time, but El Paso and Hudspeth County in far west Texas use Mountain Time. El Paso is geographically closer to Los Angeles than to Houston \u2014 and is closer to three state capitals (Santa Fe, NM; Phoenix, AZ; Chihuahua, MX) than to Austin.
Texas's energy industry runs the state like a country: if Texas were independent, it would have the 9th largest economy in the world. The Texas power grid (ERCOT) is unique \u2014 it's not connected to the rest of the US grid, operating independently across both Central and Mountain time zones.
NASA's Johnson Space Center in Houston operates on CT \u2014 “Houston, we have a problem” was transmitted at CST. Austin's tech boom (Tesla, Oracle, Samsung, SpaceX) has made it “Silicon Hills” \u2014 attracting workers from California who gain 2 extra hours relative to Pacific Time colleagues.
