Hi,

we need to track overtime of employees. Basically Odoo does this correct, when changing working time for a single day, the overtime is calculated correctly.

What I'm missing is a way to view and edit the overtime manually. Why? When an employee changes from e.g. 40h to 35h per week, I need to change the working time model exactly on the day where the employee switches. If then he has to correct something in the past, overtime would also be calculated wrong.

Even better would be a field "expected hours" and "actual hours" for each attendances entry. 

I was able to add a new "overtime" menu with model "hr.attendance.overtime" - that at least gives me access to required fields.

How do you handle these cases like changing contract for an employee, fixing wrongly booked overtime, etc.
