How to define a stop period during the business day

I am using the TTMSFNCGanttChart to define a task like below:

Start Date: 05/01/2025
End Date: 05/01/2025
Start Time: 07:00 am
End Time: 5:00 pm
Start Lunch time: 11:30 am
End Lunch time: 12:30 pm
Total Work Time: 9 hours and 1 hour to lunch.

I need to subtract the 1 hour because the task is stopped and when I send start/end time to the component the result is 10 hours not 9 hours.

How to deal with it?

Regards.

This can be set witht the WorkTime property of the Project.
Where you can add 2 time spans from 7h00-11h30 and 12h30-17h00.

For the moment this is for the complete project and can not yet be customized by task.
