cp -p not preserving timestamp

[ambaraba]

I would like to cp a file created in 2002 (linux mint 21.2)
from srcdir [local HDD "UUID=5AAAA.. /mnt/srcdir ntfs-3g" in fstab]
to destdir [network share "//192.168.xx.xx /mnt/destdir ... cifs ..." in
fstab]
preserving the original creation date (2002)

cp -p /mnt/srcdir/FILE.jpg /mnt/destdir/FILE.jpg

Unfortunately the timestamp on the destination is not preserved (it is
TODAY !)
For sure I'm doing something wrong ... but cannot find where and what
THANKS for any help !
P.S.

cp -p /mnt/srcdir/FILE.jpg /mnt/srcdir/FILE_COPIED.jpg

/mnt/srcdir/FILE_COPIED.jpg mantains the original timestamp
<grr>

boring details :

You are copying to a remote folder and the command has no ability to
manipulate the destination timestamp. That's the problem.

Se possiamo continuare in italiano chiedo:
Come copiare da disco locale a share di rete un file mantenendo il
timestamp originale ?
Ho provato "dd" e "rsync -vuart" ma in entrambi i casi la data e' quella
odierna.
Idem usando "freefilesync" :-(
Comunque : *grazie* x l'attenzione :-)

Temo che il problema sia cifs. Anzi certamente è lui, ma non so dirti se
c'è soluzione.

Dato che siamo su un gruppo it.*, la cosa strana è il primo messaggio
in inglese.

Probabilmente è il server cifs che fa orecchie da mercante.
Facendo una ricerca, vedo che ci sono stati diversi cambi di rotta
nelle versioni di Samba.

Potresti provare a approfondire sulla versione che usi lato server.

In Inglese?

Ad ogni modo, non dipende, come gia` scritto,
da "cp" solamente.

Se hai, per esempio, un filesystem *senza*
timestamp, come farebbe "cp" a mantenerli?
