applyOnlyAtCronInterval

By default, when you create a new association, the system runs it immediately after it is created and then according to the schedule you specified and when target changes are detected. Specify true for ApplyOnlyAtCronInterval if you want the association to run only according to the schedule you specified.

For more information, see Understanding when associations are applied to resources and >About target updates with Automation runbooks in the Amazon Web Services Systems Manager User Guide.
