Greenwich Mean Time emerged as a reference from the Royal Observatory in Greenwich, London, based on the average solar time at that longitude. It helped sailors, explorers, and eventually merchants coordinate maritime travel and trade routes. Over time, GMT evolved into a global standard before being overshadowed by the more precise Coordinated Universal Time (UTC). Despite this, GMT remains ingrained in common usage and global consciousness, often used interchangeably with UTC. Exploring GMT’s history provides insights into the evolution of global navigation and the unification of timekeeping.
