Mac OS X Sierra introduce clock_gettime. This breaks HAVE_CLOCK_TIME macro and corresponding get time logic. Because now Sierra has its clock_gettime function while the earlier Mac don't.
The simple fix that won't break Mac OS X earlier than Sierra is to move HAVE_CLCOK_GETTIME down and let Mac OS X condition check up. In this case, the old way is always used regardless of the existence of clock_gettime in different Mac OS X.
I tested it on Sierra and Linux. It works. In theory, it should also work for earlier Mac OS X.
