How to synchronize folder date/time when using External storage SFTP


I don´t know if its meant to be that way - but my external storage connection to a SFTP Server does not synchronize the date/time aka “Modified” column - its always “seconds ago”.
The files in the Folders have their date/time transferred O.K.
