Return a Datetime object having a value that is the sum of the specified lhs (Datetime) and the specified rhs (DatetimeInterval). If 24 == lhs.hour(), the result is the same as if the hour attribute of lhs is 0. The behavior is undefined unless the resulting value is in the valid range for a Datetime object.
