Y2K Bug in BSD 2.11 Discovered
The PDP-11/70, [Oscar]’s next project " data-large-file="https://hackaday.com/wp-content/uploads/2015/12/11-70.jpg?w=702" /> A year before the arrival of the brand-new 21st millennium, the Year 2000 Bug was predicted to grind modern society to a halt and ensure that at the dawn of the year 2001, there’d be nothing left but the smoldering wreck of once great societies. Thanks to the concerted efforts of countless engineers, software developers, and many others, we were left wi
A Y2K-related bug was found in the BSD 2.11 operating system, involving a specific time synchronization issue. The bug was identified through an experiment using an old PDP-11/70 computer and a time signal receiver. The problem arises from the use of 20th-century year formatting in the system's code. While not a critical issue today, it highlights how past programming assumptions could lead to errors. The discovery serves as a reminder of the challenges in handling date-related data. It also underscores the importance of addressing similar issues in modern systems. The bug is largely of interest to retrocomputing communities. The finding is relevant as new date-related problems, like the 2038 issue, approach.
It highlights the ongoing challenges of date-related programming issues and the importance of learning from past mistakes.
