Overtime per week vs. per day

Overtime per week vs. per day

In the United States 90% of the states calculate overtime as working more than 40 hours per week. It appears that Zoho People can only calculate overtime per day.  How do we fix this?

Here is an example:

Mon      8 hours
Tues      7 hours
Wed      9 hours
Thur      8 hours
Fri            8 hours
-----      
Total      40 hours (no overtime)

However, Zoho people says 1 hours of overtime because the employee worked 9 hours on Wednesday. Maybe I have something setup wrong in Zoho People?
