What solutions are there for programs that can’t be recompiled because the source code is not available? Think for example of old games.

Probably changing the system time, or faking the system time, so that these programs do not run into issues.

Probably a backwards compatible runtime that uses 32-bit timestamps which fills in a fake time after 2038 (e.g 1938). For example steam ships different runtimes, as does flatpak.
