The job timeout function is a perinate issue on the the Alteryx server because scheduling workflows on the server that overlap with another workflow can cause bottleneck issues. Depending on the number of workers and the other workflows, the workflow in question could fail to run or not complete running at the desired date and time. I recommend a view option of the Schedule Forecast feature for all users, so as to allow all users to effectively schedule workflows on the Alteryx server that do no conflict with other workflows.
