A (scheduled) window is a time range in which deployments are allowed to a particular environment. Time range is defined using cron expressions. Deploy or Execution request when submitted will be scheduled to run during next available window and it will execute (provided no other approval is configured) when scheduled window is reached. Deploy or Execution request submitted with Start Time that falls outside of the window will require the approval of a configured approver. If current time is already in scheduled window, then deploy or execution request will not have to wait for next scheduled window.

Cron expressions are comprised of 6 required fields and one optional field separated by white space. The fields respectively are described as follows:
