As far as I know, the finest level of control for WRKJOBSCDE is a specific 
time, on a given day or set of days.

I resorted to writing code to do this - something like this:

  do while true;
    startTime = current date and time;
    run repeating process;
    endTime = current date and time;

    runTime = (endTime - startTime) in seconds;
    delay job (time between executions - runTime);

  end loop;

This is for an "never ending" job.  If you wanted to run only during 
certain hours, you could pass an end timestamp.  Then, 

  runTime = (endTime - startTime) in seconds;
  delay job (time between executions - runTime);


would become

  runTime = (endTime - startTime) in seconds;
  nextRunTime = endTime + (time between executions - runTime);
  if (nextRunTime < scheduledEnd);
    delay job until nextRuntime;
  endif;

I think other solutions have been discussed in the past as well.

Hope this helps,
Adam
