Why is UTC used as the global time standard?
Quick Answer: UTC is used as the global time standard because it is precise, stable, and universally accepted. It combines atomic time with Earth's rotation, making it reliable for worldwide coordination without confusion from daylight saving changes or political time zone shifts.
UTC stands for Coordinated Universal Time and is based on atomic clocks, which are extremely accurate. Unlike GMT, which is a time zone originally tied to the Prime Meridian, UTC is a time standard used globally for consistency.
This standard helps keep clocks synchronized everywhere, which is crucial for things like air travel, the internet, and international business. Plus, UTC doesn't change with seasons, so it avoids the confusion that comes with daylight saving time.
