Time-Calculating amount

(Attached) I have done a lot of research, but have not seen an easy way to have a formula take into account the next day. I don't want to have to type in the date and the time. I need a formula (In the D column) that will take start and stop times and tell me how much time was spent. Many times will cross over until the next day. I can do military or regular time.


Thanks,
Jay
