# Breaking: #65165 - AdditionalMethodsInFolderInterface {#breaking-65165-additionalmethodsinfolderinterface}

See [forge#65165](https://forge.typo3.org/issues/65165)

## Description {#description}

The interface `FolderInterface` has received two additional methods. Classes that implement
`FolderInterface` have to implement those methods as well. The new methods are:

-   `getModificationTime()` \- Returns the modification time of the folder as Unix timestamp.
-   `getCreationTime()` \- Returns the creation time of the folder as Unix timestamp.

## Impact {#impact}

Classes implementing the `FolderInterface` no longer fulfill the requirements of the interface.

## Affected Installations {#affected-installations}

Installations that use custom implementations of the `FolderInterface`.

## Migration {#migration}

Implement the two new methods in custom implementations of the `FolderInterface`.
