WC operation time vs shift time

Dear Experts,

I have 2 shifts defined in my wc, S1 - 6.92 hr and s2 7 hr. But my wc operation time is from 07:00:00 am to 16:00:00 pm (8.33 hrs). Also in intervals above appears with standard available capacity 'X' interval. How does it effect the scheduling/capacity planning ? Do I need to change wc operation time according to shifts? What is the impact?
