After a couple of typos, I started using the symbolic names instead. :)
Like

   if job_desc.time_limit == slurm.NO_VAL then
  slurm.log_info("job from uid %d with missing time: Denying.",
 job_desc.user_id)
  return 8000 -- Signal ESLURM_MISSING_TIME_LIMIT
   end

4294967294 is the special value slurm.NO_VAL, meaning the parameter was
not specified.  It is for 32 bit parametres.  I guess (but haven't
double checked) that 65534 is slurm.NO_VAL16, meaning the same for 16
bit parametres (there is also a slurm.NP_VAL64 for 64 bit parametres).
