In this example, we demonstrate adding a timeout to the job's agenda items and then a callback that will fail the agenda item based on the triggering of the timeout.
This script will submit a job with a 30 second, agenda-based timeout that runs a bunch of "sleep" commands. Each agenda item will do exactly nothing for a number of seconds equal to the frame number. Timeouts have a resolution of about 15 seconds, so you should start seeing agenda items timeout at around frame 30-50, and then timeout consistently beyond that (or until the job is auto-wrangled away, assuming auto-wrangling is enabled).
