🇨🇳 Tianjin

A major port on China's northern coast near 39 degrees north latitude, Tianjin has a population of roughly 11.1 million. It follows China Standard Time, the country's single UTC+8 offset, and observes no daylight saving, keeping local clocks eight hours ahead of Coordinated Universal Time all year. Lying in the Northern Hemisphere close to the national capital, the city shares its official time with the rest of the mainland, from the eastern seaboard to the western interior. Its fixed offset means the gap between local and international time never varies with the seasons, simplifying coordination across the country's wide east-west expanse.
