Tweet ghim
I figured out why Eikoh Kano’s tweet showed the date September 2, 1992.
The tweet was actually posted on December 11, 2011 at 10:02:50 (Japan time).
When converted to Unix time (milliseconds), it becomes:
1323565370000
But this number was mistakenly treated as a 32-bit unsigned integer, which is too small to store such a large value.
So it caused an overflow, and the system instead used:
1323565370000 mod 2³² = 715442832
This smaller number corresponds to a date in 1992, which is why the tweet appeared to be from that year.
