Notification schedule
A node can configure specific days and times that it will receive notification of orders for shipping.
For example, a node could specify that it can receive notifications only at 9:00 a.m. Monday through Thursday.
This affects the notification time because, even if the node is capable of shipping two hours after receiving a notification, it cannot receive notification on Fridays. This notification schedule will force the notification to the following Monday at 9:00 a.m.
