[FEATURE] Append Current Timestamp to Every Output

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

In multi-tasking workflows, being able to clearly associate outputs with a specific point in time is highly valuable. To support this, I propose that every response generated by Claude Code should automatically end with a timestamp.

Ideally, this feature should be configurable, allowing users to choose:

Whether to include both date and time, or time only

The timestamp format (preferably derived from the operating system’s locale and formatting settings)

To ensure accuracy, the timestamp must always be generated dynamically. Specifically, the system should execute the date shell command immediately before appending the timestamp to each response. Cached or estimated timestamps must never be used.

This feature would significantly improve traceability, especially in environments where multiple tasks or outputs are handled in parallel.
