A number of you will have noticed already that the 64-bit time_t transition is now in progress in Debian experimental.

The goal of this transition is to ensure that 32-bit architectures in trixie (whether they are currently release architectures, or out of archive, etc) will be capable of handling current and future timestamps referring to times beyond 2038.

Is it bad that I thought this had already been done?
