Hi JerryMan0018, Based on what you've described, it seems like there might be an issue with how the assistant is calculating or presenting date and time. While there isn't a specific changelog entry regarding future date calculations, here are a few steps you can consider to troubleshoot the issue: 1. **Review Date and Time Settings**: Ensure that your system settings, particularly timezone configurations, are correctly set as they can impact how time is displayed and calculated. 2. **Update to Latest Version**: Make sure your system and any relevant API components are updated to the latest version. This can include updates mentioned in the [June 4, 2025 changelog](https://docs.vapi.ai/changelog/2025/6/4) which might not address this directly but could affect related functionalities. 3. **Webhook Data Verification**: Check if the data sent to webhooks (like date-time information) is consistent with expected outputs. You might want to use the newly supported HMAC authentication to ensure data integrity per the [June 24, 2025 changelog](https://docs.vapi.ai/changelog/2025/6/24). 4. **Custom Transcriber Error Check**: If a custom transcriber is used, verify it doesn't introduce errors, as updates like the one on [October 16, 2024](https://docs.vapi.ai/changelog/2024/10/16) have improved error tracking which might help in identifying issues. If you identify a specific error code or scenario, feel free to share for more targeted assistance.
