While setting up attendance rules, you need to select the shifts, one shift can set up to 3 times clock in & out. The shift can be edited both on mobile client and the desktop client:

1. Mobile client:   [Work] Tab > [Attendance] > [Settings] > [Add Attendance Group] > create a [Group Name] > click [Next] and go to [Rule Settings] > click [Att. Time] > click [Edit] icon on the right side of the shift name to set up the working time. If you have created the attendance group already, you can also edit the shift by clicking [Edit Rules] > [Att. Time] . (Only admin has access to Attendance setting)

2. Desktop client: you can edit the shift by logging into admin panel (oa.dingtalk.com) > [Applications] > [Attendance] > [Attendance Settings] - [Shift Management]

Tips:

After you modified the shift, the attendance group which has adopted this shift will be changed synchronously.
