s32 unix clock

From: retr0.id
It is now ??????????.??? (????-??-??T??:??:??.???Z) in Unix time, according to your local system clock.

That's ??.????????% of the way between -2147483648 (1901-12-13T20:45:52.000Z) and 2147483648 (2038-01-19T03:14:08.000Z) - the latter being unrepresentable as a signed 32-bit integer, off by one.

Representing it in hexedecimal, we get ????????

When the red hand points straight down (hex 80), we'll have hit the 2038 problem.
