Is this the world’s oldest tweet? Viral X post in Japanese shows impossible 1992 timestamp

Marking 20 years since Jack Dorsey’s first tweet, a post by Japanese comedian Eiko Kano recently went viral for showing a date of September 2, 1992, long before Twitter, now X, existed. While the post appears older, some users suggest it may be from 2011. The unusual display has sparked playful “time travel” theories and renewed interest in the platform’s history.
