Schedule validation
The schedule validation functionality checks that the employee is scheduled to work at the time of the clock punch. If an employee attempts to punch in when they are not scheduled, the punch is rejected with a validation message. For example, if the employee is not scheduled for today but has a future schedule, the message Not Scheduled Until MM/dd/yyyy HH:mm is displayed on the clock.
          Depending on your system configuration, you can enable schedule validation in one of the two places:
          
         - If you are using the Readers form, select the Enable Schedule Validation check box. 
            See Adding clock readers. 
- If you are using Reader Configuration in WFM, use the validation.schedule.enableproperty in the configuration.
          Note: 
          
         
         For each employee who requires schedule validation, you must select the check box for the employee badge.
Grace period
           You can define a grace period for schedule validation before and after the employee's scheduled time. 
           
          - Start grace time specifies the number of minutes before and after the scheduled start time that an employee can clock in.
- End grace time specifies the number of minutes before and after the scheduled end time that an employee can clock out.
           The grace periods apply to the following swipes in swipe order validation:
           
          - Start Grace: Applies to Clock IN swipes and a non-break time code change that serves as the beginning swipe of a shift.
- End Drace: Applies to Clock OUT swipes.
            Note: If a swipe is made outside of the employee’s scheduled time and the grace periods, the swipe is rejected if 
          accept_when_no_schedule is set to N.
           
           Grace period configuration depends on how your system is set up:
           
         - In the Readers form, use the and fields.
- If you are using Reader Configuration in WFM, use the validation.schedule.start_grace_in_minutesandvalidation.schedule.end_grace_in_minutesproperties.
