Issue: we're trying to limit jobs to a particular amount of CPU time. I'm not sure of the relationship between JOB time and STEP time. I understand that TIME=3 on the STEP limits that step to 3. With 5 steps, what is the limit for the whole job?

And that CPU Time not clock time. So each step no more than 3 minutes. 3 mins 1 sec it fails on that step. So is there a specific issue you are trying to resolve?
