Time is possibly the most fascinating aspect in our universe, Pat.
In some ways, I follow the ancient Greek delivery (partially because it is written in a way I can easily understand): Chronos existed before Zeus, being his father. When grown, Zeus challenged his father and came out victorious. Chronological order is still the order, but takes in a subdued position to that of space. In the pentaist Big Bang, time arrived before space arrived, but space is the more dominant feature of our universe, not allowing time to reverse itself (though it does seep backwards, too. See later below).
In time, there are also two dimensions, and just like the spatial dimensions they are the context in which reality takes place. The field dimensions of time, and I hope you forgive me for the rather ordinary words, are 'past' and 'future.' They are the context in which the contents of 'the present' takes place. Past and future do not exist, they are only contexts for the only time feature that does exist.
Past and future are connected like the two spatial dimensions are connected; there exists a forced element that creates the spatial left and right sides, and a forced element that creates the time features of past and future. Please understand that a single dimensional field is a fake/art dimension, reality is always 2D+ in which a 1D field of picture or movie can exist. Same with time, reality is always 2D+, in which a memory or an envisioned future can exist.
When seen separately, past and future are similar dimensions, just like the two spatial field dimensions are similar. Though, when viewed as such, depth is absent in both. Together both dimensions are not connected everywhere. As mentioned for space, in some respect separation 'trumps' the dual setting of the two time features, as well.
Relativity prevents me from allowing to envision a universe in which time flows backwards, for I believe relativity is itself a relative commodity unable to fully reverse an action. However, I have experienced first hand time jumps in which I saw glimpses of actual future events (mondane as they may be to other people, I found them quite shocking myself, not for the contents, but for the realization I had received an imprint from my own future, though of course I had to realize that what I saw was happening in my present and that I had seen my future in my past). My explanation is that of 'eddy-formation.' While the river of time is one-directional, eddies along the banks can flow backwards, creating little circles, but they do not influence the direction of the entire river as such. Naturally, entire rivers can meander in all kinds of directions, sometimes touching itself (creating the short cuts we call oxbows). I don't think I am standing on such a connection of one and the same river with itself, but possibly Nostrodamus was standing at such a confluxaposition.
