Thats a pointless question. You can't travel back in time. We don't even have a proper definition for "time", let alone mess with it. However, what you can try is "travel to the future" in a peculiar fashion, if it holds true at least. There are stories about people who had been lost in the woods and emerged 3 years later, only to discover that to them, only a couple of hours appear to have gone by. If such claims be taken as true, and we agree to the possibility of some forests somehow messing with our perception of time or whatever, you could "technically" travel to the future.
