26 years late and no threat unless you still run a PDP-11/70 and rely on short-wave timekeeping broadcasts

It’s been more than a quarter century since the Y2K bug threatened to disrupt the not-so-modern world, and while the patching efforts of global IT heroes prevented a millennial mess, the problem persists as a Dutch dev just found a new instance of the numeric nightmare.While working on an emulator for the venerable Programmed Data Processor (PDP) series of “minicomputer” systems manufactured between the 1950s and 1990s, Folkert van Heusden spotted an unpatched Y2K bug in the Network Time Protocol daemon in BSD 2.11.To be fair, it’s not like van Heusden stumbled onto a potentially devastating issue that’s simply waiting to cause chaos: Not only was the bug specific to the PDP-11/70, a system that entered service in 1975, but it also requires a Precision Standard Time, Inc.(PSTI) receiver manufactured by defunct hardware maker Traconex used to pick up time signals broadcast by short wave radio stations managed by the US National Institute of Standards and Technology. Even at that point, the bug won't instantly break network time, as a would-be attacker must take several steps to configure the ancient mahicnes in a way that causes the error.
