It handles multiple in and out punches per day, overnight shifts that cross midnight, unpaid lunch breaks, 12-hour and 24-hour (military) time, and punch rounding including the 7-minute rule. Hours are shown in hours and minutes and in decimal, split into regular, overtime, and double time per workweek (US federal 40-hour rule, California daily rules, or your own thresholds), with gross pay to the cent and a printable timesheet with signature lines.
