I've also tried with "freefilesync"
Unfortunately the timestamp on the destination is not preserved :-(
Is it there a way to
copy a file (many files) from local to network share
preserving timestamp ?
I'm considering "timeshift" but honestly ...
THANKS for any help

   "cp -p <whatever> <wherever>" ... preserves time and ownership.
   The '-a' "archive" mode can do the same. Experiment
   with where/when to add a trailing slash with that one.
   I've heard "touch -r" can actually do the same, but
   have never used it that way. Probably evokes 'cp -p'.
   If using some computer language's libraries to copy
   stuff you MAY have to do it in two or three steps -
   ie "get time/owner data", "do the copy", "set the
   dest file with the original info". I wrote a lot
   of backup programs - that oft stored compressed
   and/or encrypted copies - and you kinda HAD to
   do it this way just to be sure. Not HARD, but a
   couple extra steps nevertheless.
   Mosty this stuff is much easier with Linux/Unix than
   in Winders. TRY to interpret THOSE docs for the Win
   'C' library routines  :-)
