[slurm-users] How to print a user's creation timestamp from the Slurm database?

When we have created a new Slurm user with "sacctmgr create user 
name=xxx", I would like inquire at a later date about the timestamp for 
the user creation.  As far as I can tell, the sacctmgr command cannot 
show such timestamps.

I assume that the Slurm database contains the desired timestamp(?), so 
does anyone know how to print it for a named user?

The reason why I am interested in the user timestamp is that we 
repeatedly see novice users (students etc.) submitting lots of jobs 
which are broken or do not use resources correctly.  Since new users' 
jobs will have a high Slurm priority due to our Fairshare configuration, 
they quickly waste a lot of resources which could be used much more 
productively by experienced users.

My idea is to give new users some rather low resource limits (fairshare 
QOS DefaultQOS MaxJobsAccrue GrpJobsAccrue) initially.  After a test 
period of a few weeks or months, I could increase their limits to our 
normal default values.  If I had a timestamp for the user creation, I 
could use my scripts to automatically update the user limits after the 
test period had expired.

I have thought of recording user creation timestamps outside of Slurm by 
creating a stop-file in the filesystem whenever running "sacctmgr create 
user name=xxx".  This would probably do the work, but I prefer to use 
only the Slurm database information whenever possible.

Does anyone have other ideas about how to accomplish such a setup?
