Debian is proactively addressing the upcoming Y2K38 bug by transitioning to a 64-bit time representation for most hardware in its upcoming Debian 13 "Trixie" release. This change aims to prevent potential failures related to the Unix Epochalypse, which occurs when the 32-bit signed integer representing time overflows in January 2038. However, the oldest hardware will continue to use the existing 32-bit time representation for compatibility.
