Clearly visualise the 24-hour times by using four types of analogue clocks and two types of digital clocks.
Press the cursor button in the toolbar to control the tool. The clock starts from current time and can be used as instructional clock. Move the hands of the analogue clock and the digital clock copies the altered time. Change the time of the digital clock with the '+' and '-' buttons and the analogue clock copies the altered time.
Click on 'Reset' to set the clocks to the current time.
