27 atlas cities
All these cities share a single clock time despite spreading across a wide range of longitudes. Most Vietnamese and Javan cities sit east of the zone's meridian, so the sun peaks before clock noon there, while Bangkok, Phnom Penh, Vientiane, Novosibirsk, Krasnoyarsk, and several Sumatran cities lie west of it, where solar noon comes later on the clock.

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