Override
An override is a temporary exception to a schedule: it keeps a resource or group running, or keeps it stopped, regardless of the schedule, until an expiry time you must set. When it expires or is cancelled, the resource follows its schedule again. Why it matters: It lets people handle a late release or an urgent shutdown without editing the schedule everyone relies on.
