You need to write a scheme routine to extract that information and put it into a parameter. 

I think it is better to write a C routine like DEFINE_ADJUST / DEFINE_REPORT_DEFINITION_FN where you can track the time required and store that in output parameter.

Or you in Journal/Scheme you create a first placeholder for time, you run you create a second helper to store end time and then do end-time - start-time and put that in a scheme driven output parameter. The User's Guide does provide insights on how to define Scheme driven Output Parameters.
