Hi, I checked the JobInProgress.java class, i see as you said there is no counter as "Total Job Time" there, but there are two different variables ,one called "finishTime" another called "startTime" .I guess if i add (finishTime - startTime) to logJobSummary method that may give us the "Total Job Time" .Am i right ?
