Seconds vs milliseconds
What this is
JavaScript Date.now() is milliseconds. Python time.time() is seconds (float). JWT exp is seconds. Mixing them shifts dates by ~500× the age of the universe in the wrong direction — or to 1970 plus a few weeks. This converter guesses by magnitude: |n| < 1e11 → seconds.
