What does 'clock' mean on a car?

[McRafael]

On a car, 'clock' refers to the clock function. The purpose of having this button in the vehicle is to allow the driver to quickly switch the screen to the clock interface while driving, enabling them to check and set the time. There are various buttons inside the car, and the more high-end the car, the more buttons it has. Except for a few domestic cars, most vehicle button labels are represented by English letters. The meanings of common car English buttons are: CLOCK (clock), INFO (information), FAV (favorites), TONE (tone), AS (auto search for radio stations), BACK (back), BAND (band), CD/AUX (CD audio interface/switch), CONFIG (configuration).
