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