About Houston
Houston is the largest city in Texas and a global centre of the energy industry, with the headquarters or major offices of many oil, gas and renewables companies. It is also home to NASA's Johnson Space Center, the vast Texas Medical Center and one of the busiest ports in the United States.
The city is on Central Time: CST at UTC-6 in winter and CDT at UTC-5 in summer, after clocks go forward. Houston keeps the same time as Chicago, Dallas and New Orleans and is one hour behind New York. Texas is not entirely on one clock, though: El Paso, in the far west of the state, follows Mountain Time.
