samba - Nov 2011 - Preserving timestamps with smbclient

I have a backup script that uses smbclient to push files to a Windows
server and I have noticed that the mtime on the server is the time of
upload, not the mtime of the original file.  I can not find an option to
preserve the original mtime.  Does such a thing exist?  Shouldn't it do
this by default?

Hallo, Phillip,

        cp -a
        rsync

Viele Gruesse!
