scheduleAt

When to schedule the action.

• NOW - Immediately schedules the update to happen in the current hour if there's capacity available.

• TIMESTAMP - Lets you specify a custom date and time to apply the update. If you specify this value, you must also provide a value for DesiredStartTime.

• OFF_PEAK_WINDOW - Marks the action to be picked up during an upcoming off-peak window. There's no guarantee that the change will be implemented during the next immediate window. Depending on capacity, it might happen in subsequent days.
