No, because if she was able to provide that much information as a conscious communication, she will have provided enough information to have affixed her departure at a specific time.
In any case, there’s probably some reason that would make it impossible for her to convey that much information inside 6 hours, anyhow.
Scenario A: Amelia Bones comes back from six hours in the future and provides large amounts of evidence of this fact, and of what happens.
Scenario B: Due to quantum randomness, a large number of particles happen to jump into the spot to create a clone of Amelia Bones who believes she is from the future and carries evidence of this.
It is, again, impossible for Dumbledore to tell which of these situations happens. Yet the time turner does not work.
It’s very possible for to distinguish the two situations. The same probabilistic mechanism that determines the arrow of time precludes scenario B. Also, it’s not really that Dumbledore is actually doing the distinction. It’s more if he could do it.
It doesn’t preclude scenario B. It just makes it unlikely. The same could be said about the original scenario A. It’s possible that Amelia Bones was mistaken about when she came back, but it’s unlikely. The probability is more extreme, but the information is still there.
It doesn’t preclude scenario B. It just makes it unlikely.
I have a “Many Worlds/QM” style interpretation of time turner mechanics. Basically, all of the possible interpretations of the information+metainformation you have transmitted via time turner “exists” or is in a kind of superposition, until receiving information precludes them. Making Scenario B overwhelmingly unlikely is precluding it.

How about this:
Scenario A: Amelia Bones comes back from six hours in the future and provides large amounts of evidence of this fact, and of what happens.
Scenario B: Due to quantum randomness, a large number of particles happen to jump into the spot to create a clone of Amelia Bones who believes she is from the future and carries evidence of this.

How unlikely does it need to be to be precluded? The given Scenario A is pretty unlikely.
Well, I note in a comment somewhere, that it would have to be a version of Amelia who was rather ditsy about time.
