Context: Temporal Data

• When used as a context-key there are fewer constraints:

• • Data must not change during use of it as a context-key
  • Data remains viable provided:
  • • It’s used within it’s update time window
    • When used as an encoding key it doesn’t produce bad payload byte values

• Must be able to predict the value of the temporal data

• Frequently changing data is not useful as a context-key

• Some timers are large enough that parts of them change infrequently
