Hi
Chandru replied about the start times.
Now if the global picture is not to run these jobs at same time but run them one by one without defining any job dependency, you should also consider Autosys Resources.
For example, define a Renewable resource with an amount of 1
In each job definition use the resource attribute to grab an amount of 1 of this defined resource.
When a first job start, it will grab this unique resource preventing the others to run. As soon as the job finished, the resource is put back in the resource pool, and the Autosys load balancer will pick it up again to run another job.
You can also refine your scheduling with the priority attribute in the job definitions.
It might help
