The Hidden Politics of Time: How Clocks, Calendars — and Now-Contentious Time Zones — Came to Be
From daylight saving time to China’s single time zone, governments and railroads have used clocks to shape daily life and national control.
The House of Representatives last month passed legislation to make Daylight Saving permanent year-round, though Senate prospects for passage remain low.
In 1883, The American Railway Association standardized time zones across America, replacing more than 40 city-based systems to prevent business disruptions as trains traveled between regions.
To foster national unity, the Communist Party instituted a single time zone for China in 1949; the country runs officially on Beijing time, though residents adjust local schedules daily.
Selected in 1884, the Prime Meridian runs through Greenwich, England, and was established when the British Empire held global dominance, reflecting political rather than geographic choice.
Boston University professor Elizabeth Cohen notes that "every measurement of time is arbitrary," arguing time functions as a tool societies use to manage dissent, protest, and social control.
