Oops I read

             (file+function "path/to/file" function-finding-location)
                 A function to find the right location in the file

             (clock)
                File to the entry that is currently being clocked

And took the entry (clock) for that function-finding-location 

My bad.

I have to read and understand the role of that function better.
