# Specification: add-local-time-and-query-token

## Context
The task is needed to add local time and a unique query token to the API responses for logging purposes and to prevent duplicate requests.

## User Scenarios
1. **<Scenario 1>:** A user sends a request to the API, and the response includes the current local time and a unique query token.
2. **<Scenario 2>:** The logs show the local time and query token for each request, allowing for easier debugging and tracking of duplicate requests.

## Functional Requirements
- FR-01: Implement a function that adds the current local time and a unique query token to the API response.
- FR-02: Update the logging mechanism to include the local time and query token in each log entry.

## Non-Functional Requirements
- NFR-01: The implementation should not affect the performance, availability, or scalability of the existing system.

## Boundaries (what is NOT included)
- <explicit exclusions>
  - This task does not include changes to the API contract or user interface.

## Acceptance Criteria
- [ ] The API responds with the current local time and a unique query token for each request.
- [ ] The logs include the local time and query token for each request.
- [ ] The implementation does not affect the performance, availability, or scalability of the existing system.

## Open Questions
- <questions to be resolved in the Clarify phase>
  - How will the unique query token be generated?
  - Where should the local time and query token be added in the API response and logs?
  - What is the acceptable format for the local time and query token in the API response and logs?
