Gnulib module: time

Portability problems fixed by Gnulib:

  * This function is not consistent with gettimeofday and timespec_get on some platforms: glibc 2.31 or newer on Linux, FreeBSD 12.2/sparc64, AIX 7.2, native Windows. Namely, in the first 1 to 2.5 milliseconds of every second (or, on AIX and Windows, in the first 5 milliseconds of every second), time returns a value that is one less than the tv_sec part of the return value of gettimeofday or timespec_get.
