Here are some of the diagrams I created for my work in the philosophy of time. You can see versions of them in my Philosophy of Time and Perceptual Experience and in my Philosophy of Time: A Contemporary Introduction. These are diagrams of temporal experience under different concepts of time, i.e., retentionalism and extensionalism under tense theory and tenseless theory.
These diagrams are of my own making. I am very happy for anyone to use these if they wish to do so. However, although I’m sure the following is obvious, if you do use them, please let me know (a link would be great, too) and acknowledge their source (i.e., here) in your usage. And, of course, thank you for using them.

1 Retentionalism
Very rough definition: Time-consciousness, including the experience of duration (or of things happening over a duration) can be explained by a tripartite structure in consciousness composed by:
(i) A primary impression (for the immediate or immanent present),
(ii) A retention (for the just-past) and (often left out in discussion)
(iii) A protention (for the near-future).
1.1. Basic
Retention–Basic. An attempt to leave out A-series and B-series reference in the model. (Not sure it is successful).
1.2 In the A-series and B-series
Retentionalism in the A-series. In real fudnamental time if A-theory is true (but not if B-theory is true).
Retentionalism–B-series. In real fundamental time if B-theory is true (but not if A-theory is true).
2 Extensionalism
Very rough definition: Time-consciousness, including the experience of duration (or of things happening over a duration) can be explained by consciousness extending over that duration (of things happening).
2.1 Basic
Extension–Basic. An attempt to leave out A-series and B-series reference in the model. (Successful?)
2.2 in the A-series and B-series
Extensionalism–A-series. In real fundamental time if A-theory is true (but not if B-theory is true).
Extensionalism–B-series. In real fundamental time if B-theory is true (but not if A-theory is true).
