The Linux kernel has supported the CONFIG_COMPAT_32BIT_TIME Kconfig build time option for optionally disabling of legacy 32-bit time system call support.
This is intended to disable the code that uses a 32-bit integer for time that is thus not Year 2038 safe, but at the cost of breaking compatibility for legacy 32-bit applications.
Even if building without Linux 32-bit time support, it turns out some 32-bit time code persisted but that is now being fixed with Linux 7.3...
