A feature of the dashboard of most modern motor vehicles is its clock. Having a clock on the dashboard is a useful way of keeping track of the time without the driver having to remove a hand from the steering wheel. There are two main types of clock in a car, the digital clock and the analogue clock.
Originally, the analogue clock displayed the time by way of a fixed hand and a rotating dial. This was later superseded by a rotating hand on a fixed dial, which remains the present convention.
An analogue clock in a motor vehicle, therefore, normally displays the time by way of a face and dials. Analogue clocks were first developed many years ago and have taken many forms. Most analogue clocks have a circular scale of twelve hours. The minute hand of the clock displays the number of minutes past the hour and, if the analogue clock has a second hand, this will display the number of seconds past the minute. Although the majority of analogue clocks display twelve hours there are some that show a twenty four hour cycle.
The analogue clock runs on the battery of the car, so if the battery is removed or becomes flat, the clock will cease to operate and the time will need to be re-set.
