For many systems time_t is a 64-bit time, and most of the world will go there for 32-bit systems as well, naming that new type __time64_t for example, as described for glibc at <https://sourceware.org/glibc/wiki/Y2038ProofnessDesign> You can ask whoever provides your <time.h> what their plans for y2038 are. Sorry we cannot help you. Good luck, Segher
