UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks and time. It is the basis for civil time today, replacing the Greenwich Mean Time (GMT) in 1972. UTC is kept using atomic clocks, which are the most accurate timekeeping devices invented. Despite its name, UTC is not set to the time of any particular place. Instead, it is a global time standard that is used for a range of purposes, including coordinating international travel, scientific research, and financial markets.
UTC is important because it provides a common reference point for timekeeping around the world. This helps to avoid confusion and errors that could occur if different countries and regions used different time standards. UTC is also essential for many modern technologies, such as GPS and satellite communications.
UTC is the foundation for local time zones around the world. Each time zone is a specific offset from UTC, typically in one-hour increments. For example, Eastern Time (ET) in North America is 5 hours behind UTC, while Central European Time (CET) is 1 hour ahead of UTC. By using UTC as the basis for local time zones, it is easy to determine the time difference between different parts of the world.
