+Enforce a time limit on a step.
+
+Any step can have a hard time limit enforced by attaching timeout and the number of seconds to limit it to.
+
+	timeout: duration
+
+The amount of time to limit the step's execution to, e.g. `30m` for 30 minutes.
+
+When exceeded, the step will be interrupted, with the same semantics as aborting the build (except the build will be `failed`, not `aborted`, to distinguish between human intervention and timeouts being enforced).
+
+The following will run the task, and cancel it if it takes longer than 1 hour and 30 minutes:
+
+	plan:
+	- get: foo
+	- task: unit
+	  file: foo/unit.yml
+	  timeout: 1h30m
