Attendance time of #1
employee
Statistical result based
on attendance rules
Description: The attendance time 12:50 is adopted based on the principle of adopting a median in the attendance time
range. For the attendance time range from 9:00 to 12:00, the normal check-out time range for the off-duty time 12:00 is
from 12:00 to 12:30 (that is, 12:00 + (13:00 - 12:00)/2). But there is no check-out time during this time range, therefore, the
check-out time is blank. The normal check-in time range for the on-duty time 13:00 is from 12:30 to 13:00, and the
check-in time 12:50 is during this time range. Therefore, the check-in time of the employee is 12:50. The calculated time of
attendance is shown in the preceding table.
Case 2:
Attendance time of #1
employee
8:50, 11:55, 12:20, 18:01
Statistical result based
on attendance rules
Description: The time 12:20 is adopted based on the principle of adopting a median in the attendance time range. The
normal check-out time range for the off-duty time 12:00 is from 12:00 to 12:30 (that is, 12:00 + (13:00 - 12:00)/2).
Therefore, the check-out time of the employee is 12:20. The normal check-in time range for the on-duty time 13:00 is from
12:30 to 13:00. But there is no check-in time during this time range, therefore, the check-in time of the employee is blank.
The calculated time of attendance is shown in the preceding table.
