Debian plots fix for Y2K38 bug by upgrading to 64-bit timekeeping

techspot.com Alfonso Maruccia 2025-12-23 03:13:00

The big picture: On January 19, 2038, at 03:14:07 UTC, certain Unix-based computer systems will encounter a critical timekeeping failure. Due to a software flaw known as the "Y2K38 bug," 32-bit Unix-like operating systems will reset their internal clocks to the start of the Unix epoch – January 1, 1970 – and begin counting time from there again. While the consequences could be widespread, developers are already working on fixes to ensure systems continue to track time correctly. The Year 2038 p
