It's not so much that I'm not aware of timelines, so much as I don't really find them that relevant. The best example for me is the phrase "The other day". For most people that phrase means the recent past, but I tend to use it pretty liberally and will often say "The other day" when I mean "One day about three months ago" or something like that. It makes some of my friends laugh when they realize that I'm actually talking about something that happened a while ago.

While I hesitate to associate something like "time" to directly to Ni, I do see the point of a loose basis. I agree with Stan in the sense that I only really consider the past or future in relation to the present. That said, I see Ni as less particular about time and more about an awareness of the passage of time and how it is integrated with the dynamicism of a given event/process/idea, etc.
