The solution (NTP sync) becomes obvious. How to Apply VisualKernel Today (3 Steps) You don't need a $100 whiteboard. Use paper, Figma, or even ASCII art in your pull request comments.

"When a user logs in, the JWT token is generated, but on the subsequent GET request to the profile endpoint, the middleware rejects the token because the 'iat' claim seems to be in the future due to server clock drift." | Arrow from Frontend -> Backend | | 3
