 * The kernel writes the two-field struct timeval (tv_sec, tv_usec) that is
 * layout-identical to the public struct timeval on x86_64, so the pointer
 * passes straight through. The tz argument is deliberately ignored: the
 * historic second parameter is obsolete, POSIX.1-2008 removed struct
 * timezone, and no caller may rely on it being filled — NULL is passed to
 * the kernel, which then leaves any timezone record untouched. tv may also
 * be NULL, in which case the kernel writes nothing and 0 is returned.
