2) A time value contains Chinese characters, for example, 9：00, which differs from 9:00.

4) A time value contains special characters, for example, _9:00 and 09:-1.
The device performs validity check and error tolerance for other formats.
7. How does the K Series attendance terminal collect the correct attendance time based on the preset shift time?
A: The device collects attendance time based on the following principles:

Adopt the earliest time for normal attendance and the nearest time for abnormal attendance.

Adopt the normal attendance time if the normal attendance time and abnormal attendance time coexist.

Adopt a median in the attendance time range.
The following uses four examples to describe the preceding principles.
Example 1: normal attendance
