[kiwikami]

Isn't (some version of) Kiwikami's Hypry a bit like that?

The very first version required tenses to be marked with some agreement indicating what entity's perspective they were from - I'm planning to do the same thing with V4, but haven't figured out how it'll work just yet. Effectively, there were particles such that you'd have "the man hit [1-recent.fut] [2-pst] the dog" meaning "The man is just about to hit the dog (as far as I can see), but from your perspective he has already done so", and there was also a kind of "universal" time which was meant to describe strictly-linear progression (e.g. "from the perspective of a thing that cannot time travel").
