If a timesheet is late, can we defer OT payment to next paycheck?

Q. "Several employees habitually turn in their timesheets late. Can we tell them that if their timesheet is not turned in on time, any overtime on that week's timesheet will not be paid until the next pay period? We'd like to quit 'babysitting' employees, but don't know if taking this stand will violate any payroll laws." -- A.B., Arizona
