But in a universe with time travel, you no longer necessarily share a future or a past with the person or people with whom you are speaking. My past is your past is the world's past. When time travel doesn't exist, the past, present and future are (barring relativistic effects) absolute and universal. The first step to time travel conversations is to abandon an assumption: objectivity. Fictional universes obeying this model include The Hitchhiker's Guide To The Galaxy, Twelve Monkeys and Bill & Ted's Excellent Adventure. For the purposes of this first section, we shall assume the second-simplest model of time travel: that there is a single, perfectly internally consistent, rigid timeline, whose history cannot be altered, even though time travel is, to whatever degree, possible. In the simplest model, time travel is impossible and this entire discussion is moot. There are multiple distinct models of time travel which a universe may obey. All we need to do is obey some conventions. In fact, existing grammatical rules are already perfectly well-suited to talking about time travel. This involves the introduction of many new verb tenses and convoluted verb conjugation rules for these tenses. Dan Streetmentioner' whose own Time-Traveller's Handbook Of 1001 Tense Formations explains at great and convoluted length how to describe events in your past but another person's future, events averted through time travel, events which you are, while speaking, travelling through time to avoid, and many more.
