4 atlas cities
All four cities share a single clock time, yet the sun reaches its highest point after clock noon in each one. That means Phoenix, Ciudad Juárez, Calgary, and Edmonton all lie west of the meridian defining this zone's time, despite their differing latitudes and distances from each other. No city here sees an early solar peak.

A positive figure means the clock runs ahead of the sun — midday on the clock arrives before the sun reaches its highest point.
