Hi again,
I'm so sorry but I really couldn't understand the situation to think about solution, you're having check-in and check-out for each employee which gives me the idea that they start working at this stime and checkout (stop working), you're counting the different check in-out time and getting total,

but where's the problem happening exactly? and what kind of company is it ? what I can guess is they want to calculate the salary for each employee


sorry I couldn't understand
