// nextcloud?
// docs for file webdav
// https://docs.nextcloud.com/server/12/developer_manual/client_apis/WebDAV/index.html
// indicates checksums can be set as metadata here
// https://github.com/nextcloud/server/issues/6129
// owncloud seems to have checksums as metadata though - can read them
// SetModTime might be possible
// https://stackoverflow.com/questions/3579608/webdav-can-a-client-modify-the-mtime-of-a-file
// ...support for a PROPSET to lastmodified (mind the missing get) which does the utime() call might be an option.
// For example the ownCloud WebDAV server does it that way.
