Texas is so big it spans TWO time zones. Most people don't know this!
Houston, Dallas, Austin, San Antonio → CST (UTC−6) in winter, CDT (UTC−5) in summer.
El Paso (far west Texas) uses Mountain Time — MST/MDT — same as Denver!
A Dallas–El Paso call at 10 AM Dallas time = 9 AM El Paso time. Always 1 hour apart!
Both zones spring forward Mar 9 and fall back Nov 2 — just at different UTC offsets.
Use DCTIMEZONE to see Houston AND El Paso time side by side instantly.
