What this tool does
Night shifts work correctly: an end time earlier than the start is treated as the next day, so 22:00 to 06:00 gives eight hours rather than a negative number. The decimal result is the one payroll wants — eight and a half hours is 8.5, not 8.30.
Formula
hours = (output − down payment) − break
