Unable to repair files with ERROR: bad date 1980-01-00.

[Eitan R]

When I first run this, I get WARN: volume was not unmounted cleanly., and then I get:

ERROR: bad date 1980-01-00.

I'm willing to bet this is because I think I ejected improperly from my macOS laptop, and now Ubuntu is unhappy with me because of the timezone formatting differences.
Is there a way to automatically repair this issue?

exfatksck can't fix errors like this for now. Leaving this as TODO reminder for me.
