Attempt at formulating verb tenses when time travel is involved?

A quick Google search turns up a couple of interesting attempts:

• Time Travel Tenses
• Time Travelling Grammar

But of course I think the best way to address this is simply to wait. Once time travel is invented, people will fully sort it out and grow accustomed to it within a hundred years or so.

Those of me in the future werare frustrated with will havinged been seeing this question so many pastimeses. Please reallowed me two've preassisted you with some examples:

Subjective Present: He will have spoken

Subjective Past: He has spoken, but don't give your him guff if that instance of him doesn't remember saying it

Objective Past Perfect Progressive: He will have had been speaking- deal with it.

Hope this does haved helping.

Pasts

• I had had An event occurring prior to the jump.
• I had An event occurring at the moment of the jump.
• I had will have An event occurring after the jump, before now.

Futures

• I will have had An event occurring prior to the jump, after now.
• I will have An event occurring at the moment of the jump.
• I will will have An event occurring after the jump.

Seems most cases can be addressed by going in the following order: Speaker's time line, listeners time line, any absolute time reference.

1. Past past past (ppp): I already did that yesterday
2. ppf: I already did that tomorrow
3. pfp: I already will do that yesterday
4. fpp: I expect to have already done that yesterday
5. pff: I already will have done that tomorrow
6. fpf: I expect to have already done that tomorrow
7. ffp: I expect I will do that yesterday
8. fff: I expect I will do that tomorrow

this assumes both are speaking from the same timeline. For asynchronous communication, it can be prefaced with an indicator: As of yesterday, I already will have done that tomorrow. A note from a future speaker indicates that in the listeners' future, the speaker's past will have done an action in the absolute future.
