So basically, I want to create reports for my Attendance Records Table.
Table has :user_id, :clock_in, :clock_out, :seconds columns that are being updated.
Basically my report needs: to calculate (sum of :seconds) for a given period.
I.e. Jan 1, 2014 to Jan 31, 2014 ... I would like to list all records from this daterange, and in the end would calculate sum of :seconds.
Any ideas how would I approach this?
