Frédéric Lepied 4dc47bd3ac time_weighted_retriever: use a timestamp if needed (#9906) ... If last_accessed_at metadata is a float use it as a timestamp. This allows to support vector stores that do not store datetime objects like ChromaDb. Fixes: https://github.com/langchain-ai/langchain/issues/3685 <!-- Thank you for contributing to LangChain!
