Running 4.7.3 hardened-sources amd64/Intel corei7 causes ssl/ssh failures such as "Verify return code: 9 (certificate is not yet valid)" and others that can be traced to the above function returning "0" although clock_gettime() works just fine. This problem did not occur on older kernels, also not with the same version of gentoo-sources or with hardened-sources-4.8.15. Stephanie made a test program that shows the problem, 'T=0' on the build server: --- #include <time.h> #include <stdio.h> int main(int argc, char **argv) { time_t t; time(&t); printf("T=%ld\n", t); } ---
