23 atlas cities
All these cities share a single civil time despite spanning a wide range of longitudes. Nearly all lie west of the zone's meridian, so the sun peaks after clock noon across most of the list, from Reykjavík and Lisbon to Nouakchott, Dakar, and Accra. Only Lomé and São Tomé sit far enough east for the sun to peak before clock noon there.

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