How to program outdoor Motion / Daylight accessorie

Hi There,

Only recently started with some Hue and Zigbee devices.

Just installed the outdoor Motion/ daylight sensor.
I don’t understand the time schedules in the app.
When creating a schedule I can change the start time…but the end time is set to 23:00, it is greyed out an can not be changed.
What is the purpose for this?
I try to achieve a setting where the outdoor lights are switched on when move ment is detected.
This should happen only between for example 02:00 - 9:00
