1. Periodicity
   1. Hierarchical Periodicity
      1. Ex., Seasonality
2. Burstiness
   1. Ex., Hawkes Process
3. Stationary vs. Non-Stationary Distributions
4. Permanence / Option Structure
5. Quantized
   1. Ex. hitting lights when predicting arrival time
6. Autoregression / Autocovariance
7. Feedback
   1. Positive Feedback
   2. Negative Feedback
   3. Length of feedback loops
8. Synchronicity vs. Asynchronicity
   1. Discrete vs. Continuous
9. Exponential Decay vs. Windowing
   1. Continuity vs. Discreteness
10. Stability & Equilibrium
11. Derivatives - change over time
12. Asymmetry between past and future
13. Exclusive ability to directly impact present
14. Strong predictor of causality / anti-causality
15. Examples
   1. Skewedness in Predicting Completion Time
      1. Say, for predicting arrival time - much more likely to be early in time
   2. Time in Decision Loops
      1. Nested (Hierarchical) Decision Loops
      2. Being within another’s decision loop 
   3. Rates
      1. Information over time
      2. Distance over time
   4. Hierarchical Planning
      1. Compression over extended lengths of time
   5. Intensity (Value to smaller time window)
   6. Deadlines
   7. Time Culture / Pace
      1. Speed or Slowness of an environment or workplace
   8. Feedback (In the reward / punishment sense)
      1. Length of feedback loops
      2. Proxies for feedback to shorten length

A lot of these are about the value to slowness or quickness, it’s been hard to abstract well over time (though I suppose that ‘slow’ and ‘fast’ are abstractions about relative measures of time)

Properties

1. Association with Causality
2. Combinatorial explosion in complexity when ordering is introduced

Thoughts
1. Should I distinguish between temporal structure and sequential structure?

1. Quantized, like hitting lights for predicting arrival time
   2. Making food in a kitchen (Tempo)
   3. Dancing (Rhythmic / Periodic)
   4. Option / Permanence - School choice, Tatoos, Relationships
