Big Sur 11.5 problem - File modification dates are displayed as ten years into the future

Since upgrading to version 11.5 all the files on my Western Digital MyCloud NAS are displayed with modification dates exactly ten years into the future from their actual "last modified" dates. This appears to be a bug in the Big Sur Finder only. The actual metadata is probably uncorrupted because other operating systems that have access to that device display the modification dates correctly.

I have another file server accessed via SMB that is unaffected by this glitch.
