Temporal Dimensions in Agent Memory: How to Reconstruct Last Tuesday's Knowledge
izgorodin · reddit · 2026-08-08
The post highlights a blind spot in current agent memory systems: they can mostly answer "what was true in the world then," but struggle with "what did the agent know to be true then based on its observations."
The author draws inspiration from database concepts, specifically bi-temporal data:
- Valid time: When the fact was actually true in the world.
- Transaction time: When the system recorded that fact.
For agents, transaction time is crucial for incident reconstruction. Without it, corrected memories overwrite history, making it impossible to evaluate whether an agent's past actions were reasonable given its limited knowledge at the time. The author suggests storing claims with valid and transaction intervals plus provenance, and calls for a new transaction-time benchmark for agent memory.
