Yes. Or that a contract was not created before a certain date. Or, as another poster suggested, that a photo of a damaged rental car was taken before you took possession of the car.
you're right, it can be used to prove that a contract with both signatures existed before a date, not after. So if Alice makes an agreement with Bob, Alice can't turn around and say that the contract was only ratified after Alice failed to meet certain obligations.
Then again, digital signatures come with a timestamp, Alice could lie about that timestamp, but it would be obvious to Bob that she did.

So, if I could automate this, could I use this to prove in court that logs were created, and not tampered with?
Just trying to think of practical uses of this cool project, and it's the first thing that came to mind.

I think you have that one backwards. You can demonstrate a contract did exist at a certain date. There is no proof of non-existence before that date.

Fun to think about.
