The host shares a directory (/mnt/Lokal/VM_share) with the guest.
On the host system I have (in my home directory) a file
> ls -la *.jpg
-rw-r--r-- 1 A users 40749 Mar 3 2023 Opensuse_beer_label.jpg
when I copy this file to the shared directory
> cp -a Opensuse_beer_label.jpg /mnt/Lokal/VM_share/
everything looks fine (on the host)
> ls -la /mnt/Lokal/VM_share/

The timestamps in the share of the VM don’t make sense to me.
This happens to all files copied to the share.
Even when I copy files in the guest to the share their timestamps are changed
(in the share) to the current date . However when I look at those files on the
host they do have the correct date; i.e. the date of the original file in the
guest.
On MS Windows 11 (bare metal) with virtualbox 7.0.14 and openSUSE Tumbleweed
20240225 as guest I see the same behaviour.
Kubuntu (as guest) does not show this behaviour although it uses
VBoxGuestAdditions_7.0.14 as well.
I discussed this already here:
https://forums.opensuse.org/t/files-in-the-virtualbox-share-show-wrong-timestamp/172718
and a third user could very this behaviour in its setup as well.
