Gnulib module: —

Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

• This function is missing on some platforms: Mac OS X 10.11, Minix 3.1.8, mingw, MSVC 14.
• This function leaves the upper 32 bits of the tv_sec field of the result uninitialized on some platforms: mingw in 32-bit mode.

The Gnulib modules gettime and timespec_get are partial substitutes; they implement the CLOCK_REALTIME functionality of clock_gettime.
