Files in the virtualbox share show wrong timestamp

Let’s use another file for comparison on the same mount, that has different timestamps for all four of its timestamps, so that there is no ambiguity present:

Windows 10 host:

Item           : J:\other-file.out
CreationTime   : 2020-01-08T11:06:04.7240271-06:00
LastAccessTime : 2021-11-08T14:53:39.4419329-06:00
LastWriteTime  : 2020-01-08T11:06:49.3562341-06:00
ChangeTime     : 2024-04-05T18:18:19.3274703-05:00
FileAttributes : 8224

Here is how it appears on the linux guest and I have no idea why it is showing the times it is showing for the modify/access times (probably left over garbage in memory from some other file?):

michael@Kubuntu-VM:~$ stat /media/sf_J_DRIVE/other-file.out
  File: /media/sf_J_DRIVE/other-file.out
  Size: 466173          Blocks: 1024       IO Block: 1048576 regular file

As an additional cross-reference, I created a second (manually mounted) mount of the J_DRIVE share of the Windows 10 host on the linux guest running as a VM, as "$HOME/jshare", but this time with all ttl mount options set to 0 (i.e., cache nothing for file access), which looks as follows from a mount perspective (note the presence of the following options: ttl=0,dcachettl=0,inodettl=0):
J_DRIVE on /home/michael/jshare type vboxsf (rw,nodev,relatime,ttl=0,dcachettl=0,inodettl=0,iocharset=utf8,uid=0,gid=0)

On this manually set up mount with “cache nothing” mount options, running stat on the file shows us:

  File: /home/michael/jshare/other-file.out
  Size: 466173          Blocks: 1024       IO Block: 1048576 regular file
Device: 0,52    Inode: 76041       Links: 1
Access: (0777/-rwxrwxrwx)  Uid: (    0/    root)   Gid: (    0/    root)
Access: 1969-12-31 18:00:00.000000000 -0600
Modify: 1969-12-31 18:00:00.000000000 -0600
Change: 2024-04-05 18:18:19.327470300 -0500
 Birth: 2020-01-08 11:06:04.724027100 -0600

So I was mistaken, the ChangeTime is being shown correctly, whether FS caching is utilized on the guest side or not, but the Modified (i.e., LastWrite) and LastAccess times are just garbage.
