Order cutoff time allows merchants to describe the time after which they will no longer process orders received on that day. For orders processed after cutoff time, one day gets added to the delivery time estimate. This property is expected to be most typically used via the ShippingRateSettings publication pattern. The time is indicated using the time notation from the ISO-8601 DateTime format, e.g.
14:45:15Z would represent a daily cutoff at 14:45h UTC.
