Definition
The inclusion and management of time-stamped metadata within vector embeddings or agent logs to enable time-aware retrieval and historical reasoning. It allows RAG systems to prioritize recency or track the evolution of facts, preventing the model from hallucinating outdated information as current truth.
Distinguishes 'when' a fact occurred versus the 'latency' of the system response.
"A core sample from an ice sheet, where deeper layers represent older information and top layers represent the most recent state, allowing researchers to choose the specific era to analyze."
