Generate time reports by user, project, date range\n4. Add billable\/non-billable time tracking\n5. Export timesheets to CSV\/PDF\n\nTo use this time tracking system, you can call the time_tracking method with the task ID to start\/stop tracking time for a specific task. You can also call the time_report method with the desired start and end dates to generate a time report by user, project, or date range.\n\nNote: Make sure you have the necessary API endpoints and database models set up for the React app to communicate with the Flask backend.","refusal":null,"annotations":null,"audio":null,"function_call":null,"tool_calls":[],"reasoning":null},"logprobs":null,"finish_reason":"stop","token_ids":null}],"service_tier":null,"system_fingerprint":null,"usage":{"prompt_tokens":27377,"total_tokens":28064,"completion_tokens":687,"prompt_tokens_details":null},"prompt_token_ids":null,"kv_transfer_params":null}
