Files in the virtualbox share show wrong timestamp

I tested the proposed workaround. It did not work for me:

on the host:

> ls -la /home/USER_HOST/VM_Data/Open*.*
-rw-r--r-- 1 USER_HOST users 40749 Mar  3  2023 /home/USER_HOST/VM_Data/Opensuse_beer_label.jpg
>

the same file in the guest:

> ls -la /home/USER_GUEST/VM_share/Open*.*
-rwxrwx--- 1 root vboxsf 40749 Apr  3 09:43 /home/USER_GUEST/VM_share/Opensuse_beer_label.jpg
