Re: As I recall...
Clearly it's a subjective evaluation (there being no objective standard for what constitutes "time travel"), but obviously in the general case it's possible to create paradoxical situations if you have any kind of information about the future - to say nothing of the philosophical implications of predestination.
Even if you just have arbitrary access to information from the past, you can probably wrangle up an information-thermodynamic paradox of some sort. Let's see ... you could use the past for information storage, giving you more information storage than the present universe can contain; that seems dicey.
So while ACC may not seem like much of a "time travel" story, the plot device "visions of the past and future" could be leveraged into the same sort of paradoxical situations that time travel in general produces.
