-- Creates a new maintenance window.
--
-- The value you specify for @Duration@ determines the specific end time
-- for the maintenance window based on the time it begins. No maintenance
-- window tasks are permitted to start after the resulting endtime minus
-- the number of hours you specify for @Cutoff@. For example, if the
-- maintenance window starts at 3 PM, the duration is three hours, and the
-- value you specify for @Cutoff@ is one hour, no maintenance window tasks
-- can start after 5 PM.
