time limit not guaranteed to be exceeded in "Over-riding the sbatch options from the command line" section of Running Jobs with Slurm

the time limit of 70 seconds often isn't exceeded, thus failing to demonstrate what happens when the time limit is exceeded. Try increasing it to 90 seconds.

I've taught this with 120s and it has consistently worked (i.e. the job fails). I believe Slurm only checks once per minute, so any less than this has a non-zero chance of failing (to fail)
