I need my code corrected to output as well as the start and stop time

arguments entered as well as the elapsed time. Please read the assignment description and my code. I also attempted to create an absolute value on my time elapsed output, but it is showing an error. This is not a neccessary part of the assignment, so it can be taken out. But if you can fix this, I’d appreciate it. Also, please include a screenshot using  11:30:45 and 12:15:45 arguments to show the code is working. Thank you!
