Delay the start of a job in Slurm

It may sometimes be useful to submit a job and tell Slurm to defer scheduling until later. This is possible using the --begin option, which works with both sbatch and srun. The job will be submitted immediately, but only considered to run at the specified time in the future. Some examples below:

--begin=<time>

                 --begin=16:00
                 --begin=now+1hour
                 --begin=2016-06-30T12:34:00
