How do i create a report based on work log (time spent)

Hello!
we are in need of a report that details the amount of time worked (total) by a technican during whatever time period.
 
how can this be done? i do not see a summary report and i'm afraid my SQL isnt up to par to write such a query.
 
with advance regards,
LB
