I would equate time travel to being a memory and thought process. We're able to regenerate the images of events in our minds vividly when we think about past events which make us happy (e.g. child birth) or things that make us sad (e.g. manager screaming at us due to another bug crashing our software). This is time travel to the past by my definition. For time travel to the future, I think it's about predicting future events of a few seconds before they happen, based on past knowledge we've gained or learned. An example of this for me is seeing a situation where somebody is about to crash their vehicle, as the driver doesn't see another vehicle then it happens. I recall a recent fender bender like so in Manhattan during January. I knew it was about to happen given there wasn't the space then crash. So those are my definitions of time travel.
