Nope, just tried it. The machine will boot, it just takes a long time (some timeouts at play, I assume). If anything, Touch ID not working if the system time is wildly incorrect is makes me trust it more, rather than less.

Would I like the system design be more open and better documented? Sure. But if a security feature doesn't work when the clock is set 45 years in the past… is not concerning per se.

That doesn't sound quite so bad then, I'm assuming it's possible to login without Touch ID. Although it does make worry about how usable the machine will be when Apple eventually stops updating/signing the TouchBar firmware.
