Sure, that's a fair point. I'm not sure what the default behavior is on
Raspberry Pi systems.

I would urge caution about going down this route. If something goes
wrong, your file timestamps can be bogus too. You can't really trust
them any more than the system time. I experienced this personally when
my GPS got the wrong year (possibly wrong century, probably due to
issues I'll discuss in the other thread?).

I have a specific proposal that I'll hopefully write up tonight, which
may address the needs in this space.
