jobber examples: time limit

In this example the --time option is used to determine when to stop working (in a batch job).

  • A time limit in seconds is set via --time. (Alternatively, an end time can be specified with the --endtime=YYYY-MM-DDThh:mm:ss option, see the jobber batch job examples page.)
  • --time-method sets the method to determine the minimal time needed before the time limit is reached to allow the next task to be started. The value of --time-method can be either a fixed number of seconds or a factor followed by one of min, mean, and max (like the default 2max) for using the minimal, mean, or maximal past task run times.
