Global Time refers to the concept of coordinating time across different regions of the world. It is often represented by the Coordinated Universal Time (UTC), which serves as a standard reference point. Various time zones are established based on their offset from UTC, allowing people in different areas to synchronize their activities. Time zones are typically defined by the number of hours ahead or behind UTC they are. For example, Eastern Standard Time (EST) is UTC-5, meaning it is five hours behind UTC. This system helps facilitate international communication, travel, and commerce by providing a common framework for timekeeping.
