time clock data, used for calculating payroll also should be reconciled to the job time ticket data, used for costing and managerial purposes, by someone not involved in generating that data. the total time spent on all tasks, as recorded on the job-time tickets. should not exceed the attendance time indicated on an employee's time card. conversely, all time spent at work should be accounted for on the job-time tickets. finally, to ensure the validity of the data, the employee's supervisor should approve time cards and job-time tickets.
