What I see is:

* mv does preserve the time of the file, regardless of copying to an
  SMB share or not.

* cp indeed does not preserve the time of the original file, regardless
  of copying to an SMB share or not.

mv simply moves a directory entry, including the inode, from here to
there. cp creates a new directory entry at the destination. So these
results make sense.

To have cp preserve the time (i.e. copy the original file's time to the
copy), use its -p option.

Also, check for aliases that might include options you don't want.
