A timekeeping device is an instrument used to measure and track the passage of time. Common examples include clocks and watches, which display time in hours, minutes, and seconds. These devices can be mechanical, using gears and springs, or electronic, relying on circuits and batteries. Timekeeping devices have evolved over centuries, from ancient sundials to modern atomic clocks. They play a crucial role in daily life, helping people manage schedules, coordinate activities, and maintain punctuality. Accurate timekeeping is essential in various fields, including science, navigation, and communication.
