Subject: Re: preserve mtime when using FTP?

Unless I am mistaken I don't think sftp will preserve the file
metadata.  I don't know how ssh would either.  sftp and ftp use
        File.open( local_path, "wb" ) { |f| f.write contents }

After looking through the FileUtils source which can preserve metadata,
I see it just uses File.utime to set the metadata, so that is what I
will try.
