The Year 2038 problem is already in the installed base.

A signed 32-bit Unix clock dies on that second. Anything bought to last a decade past install is already inside the window. This site is the countdown, the calculator, and the list of systems still on time32.

The idea

Backwards Risk

Risk-entry date = deadline − forward horizon. A 10-year controller installed in 2018 entered the Unix Y2038 window in 2028.

Tool

Deployment checker

Give it a deadline, an install date and a service life. It tells you whether the system already intersects 2038.
