[research] LLM answers time-sensitive questions using stale training data without indicating the information might be outdated

Inject the current date into the system prompt and mandate a live web search for any query involving recent events, statistics, or changing entities.

Journey Context:
LLMs have no internal clock. They memorize facts from a specific snapshot. Even with a date injected, they often fail to realize a fact \(e.g., CEO of X company\) has changed since their cutoff. Mandatory search grounding for temporal queries is the only robust mitigation, as parametric memory is static.
