The development of time zones in the United States is closely linked to the expansion of railroads during the 19th century. Prior to that, local mean time was used, and each region effectively had its own clock. However, train schedules demanded uniformity, leading to the creation of four standard time zones—Eastern, Central, Mountain, and Pacific—in 1883. This significant step improved commerce and travel efficiency. People often explore this topic to gain insight into why time zones exist, how daylight saving came into play, and how the standardized concept of time continues to shape modern society’s coordination and productivity.
