> all you'd have to do is have someone examine it and find inode activity when you had a clear alibi that the government didn't know about (which would be easy, given we're talking 8 years here, he'd just have to find when he was on a date or out to dinner or something, the government isn't going to know his entire life history for 8 years), and you'd be well on your way to creating enough doubt with a jury.

There are plenty of ways that happens even accidentally though, a prosecutor would be able to knock out that claim easily.

You've never seen a Linux machine write entries to the system log with the wrong timestamp? It happens all the time on machines with no RTC (Raspberry Pi) or a dead battery.
