11:00 in the example below.
For example, the user can go to bed and rest in the middle of the day without the light and alarm being activated
when the person gets up.
If time control is not activated, the light is switched on and the alarm is activated as soon as the user leaves the bed.
If Time Control is active, it is displayed in the Start menu as shown in the pictures below.
Time control is disabled by default.
