// OSX is a pain. The XCode 8 SDK always declares clock_gettime
// even if the target OS version doesn't support it, so you get
// an error at runtime because it can't resolve the symbol. We
// solve that by pretending we have it here in the header and
// then enable our implementation on the source side so that
// gets linked in instead.
