The blocker application is designed to block a trigger from any resources from going to a job until the right time. This will ensure that the job can start at the appropriate time. For example, the following YAML file for Concourse has the job block-until-office-hours-on-weekdays which has specified days, timezone, start time and end time. This jobs blocks the trigger from the resource amazon-ecs-agent-image, which checks for latest version of Amazon ECS Agent docker image every 24 hours, until office hours on weekdays.
