Reporting Request

hello,
I try to generate a report to control the time filled  with the chronometer.
I want to be sure that all tasks who are in  status "finished" have an entry for the spent time.

I can do it with a custom field but i want to do this with the standard entry time.(because the collaborator can make several entries and don't need to calculate the sum of the  spent time for each task) .

 Can you introduce the information "spent time" in the tasks report because it's missing ..

Best Regards,

 

Sébastien
