With regards to the lua scripting, yes, you can modify a job and set the
time limit to something if it is not appropriate.
Treydock has one that does exactly that (among other things) at
https://gist.github.com/treydock/b964c5599fd057b0aa6a#file-job_submit-lua
You will have to distill the parts you need out of it.

I have not configured "EnforcePartLimits" in my slurm.conf file, so I
suppose that my SLURM is running with "default" value "NO", so my job
will be accept and remain queued until the partition limits are
altered (as SLURM documentation says and me too ;) )

because you may have some users have a job that does indeed need to go
that long, but they have to let you know to allow it to happen.

I think solution modifying “lua” script is a good solution. Could I do
something like this?
if time_limit > part_max_time then
slurm.log_info("job from uid %d with request for more than max_time:
Reconfiguring your job.",job_desc.user_id)
slurm.log_user("You cannot request more than %s minutes in partition
%s!!", part_max_time, partition)
time_limit=part_max_time
end
return slurm.ESLURM_INVALID_TIME_LIMIT
In other words: if a user submits a jobs with TimeLimit bigger than
partition TimeLimit, assign partition TimeLimit to his/her job.
Thanks.
