About time in Houston
Houston, the seat of Harris County, anchors the Central zone's Gulf Coast: the Port of Houston handles more foreign waterborne tonnage than any other US port, and its vessel movements, pilot boardings, and terminal gate hours are all published in Central Time.
At NASA's Johnson Space Center, timekeeping is a daily translation exercise — the International Space Station runs on GMT (UTC), so flight controllers in Houston constantly convert between the station's clock and their own CT shift schedules.
At under 30° north, Houston has one of the gentler daylight swings among big Central cities: about 14 hours at the June solstice and a bit over 10 hours in late December.

How many hours ahead of Los Angeles is Houston?
Houston is 2 hours ahead of Los Angeles in every season — Central and Pacific clocks spring forward and fall back on the same dates, so the difference stays constant.
