Getting wall time limit in bjobs

I'm writing a script that collect job information. I would like to get the wall time limit for each pending job (as specified with bsub -W) using bjobs. I can get information such as the number of cpus using a command like: bjobs -u all -p -o 'jobid user min_req_proc' But I can't find any keyword that will give me wall time. Does such a method exist? Right now I have to run bjobs -l for every job to get that information, which is very slow.
