Time signals are standardized signals used to indicate the exact time, often broadcasted by various organizations. These signals can be transmitted through radio waves, television, or the internet, allowing people to synchronize their clocks and devices accurately. Common sources of time signals include atomic clocks and timekeeping systems like the Global Positioning System (GPS). In addition to broadcasting time, time signals can also be used in various applications, such as telecommunications and navigation. They help ensure that systems operate in harmony, reducing errors and improving efficiency. Accurate timekeeping is essential for industries like finance, transportation, and telecommunications.
