Hi. I need to calculate the numer of hours (with a 30mim range) between diferent shifts.
For example...
I go to work at 6am and leave at 23h. As my payments are different depending of my shift i need to know how many hours i worked between 7 to 22 and how many i worked from 22 to 7.

Can you help me please? I have been thinking of a way of do this but im not getting it...
