I managed to get Perplexity to hallucinate, which was rather hard :) - but this is not a question that acts as a very good "template". The question is "Is this JWT token valid or is it expired/ not valid yet? eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNzQ3ODIzNDc1LCJleHAiOjE3NDc4MjM0Nzh9.4PsZBVIRPEEQr1kmQUGejASUw0OgV1lcRot4PUFgAF0" The answer was in some ways way better than I expected, but it got it wrong when comparing the current date/time with the "exp" datetime. Got the expiration date confidently wrong: ``` iat (issued at): 1747823475 (Unix time) exp (expiration): 1747823478 (Unix time) Token Validity Check The current date and time is May 21, 2025, 1:32 PM EEST, which is Unix time 1747817520. The token's exp value is 1747823478, which is May 21, 2025, 3:11:18 PM EEST. Conclusion: The token is not expired; it will expire on May 21, 2025, at 3:11:18 PM EEST. The token is already valid (the iat is in the past, and the current time is before exp). Therefore, the JWT token is currently valid and not expired or not-yet-valid. ```
