A clock is a device used to measure, keep track of, and display time. It is one of the oldest human inventions, with the earliest examples dating back to the 14th century. Clocks typically work by using an oscillator to keep track of time, which is then displayed in either digital or analog format. Clocks are an important tool for keeping track of time and can be found in many places, such as on walls, in homes, and in offices. Clocks come in a wide variety of shapes, sizes, and styles, and can be powered by either batteries or electricity.
