# Calendar.MatchingPolicy.nextTimePreservingSmallerComponents

If specified, and there is no matching time before the end of the next instance of the next higher component to the highest specified component in the `DateComponents` argument, the method returns the next existing value of the missing component and preserves the lower components’ values (for example, no 2:37am results in 3:37am, if that exists).

```
case nextTimePreservingSmallerComponents
```
