What does the CLK button in a car mean?

[MacJameson]

The CLK button in a car is the time button, which stands for 'clock'. It usually appears on the operation panel of the radio or navigation system. The purpose of this button is to allow drivers to quickly switch the screen to the clock interface while driving, enabling them to view and set the time. In some smart cars, there may also be system time for the in-car multimedia and the CAN network time of the vehicle itself. Method to set the car time: 1. Press and hold the CLOCK button until you hear a beep, then release the button, and the time display will start flashing; 2. Set the hour by pressing and holding the preset button's H end to select the correct hour; 3. Set the minutes by pressing and holding the M end to select the correct minutes; 4. Finally, press the CLOCK button to complete the setting.
