hi there, 

under timeregistration u can choose to see week view for your registration. on this week view u can se total hours worked. as a default its set to that u can work 8 hours a day. which is marked with green. when u work more than 8 hours it turns red.

is is possible to change this default value to something else? 

and under reports, week repport for employee. the total time worked in a week is shown as overtime.....

where to change and choose this overtime?
