Why We Have Time Zones Instead of One Global Time

Subject: Static GK (General Knowledge)

Book: General Time Knowledge

A single global time could simplify international collaboration, but most societies prefer a local clock that aligns with sunrise and sunset. Daily routines like meals, work shifts, and school hours hinge on daylight patterns, making universal time impractical for everyday life. Critics argue a standardized reference like UTC should replace local variants, yet cultural attachments to the sun’s position persist. The tension between convenience and tradition is evident in debates on daylight saving, half-hour offsets, and synchronous working hours. Understanding these factors clarifies why time zones endure in modern civilization.
