#else // __APPLE__
-// FIXME: We assume that clock_gettime(CLOCK_MONOTONIC) works on
-// non-apple systems. Instead, we should check _POSIX_TIMERS and
-// _POSIX_MONOTONIC_CLOCK and fall back to something else if those
-// don't exist.
+// FIXME: if _LIBCPP_HAS_NO_MONOTONIC_CLOCK, then clock_gettime isn't going to
+// work. It may be possible to fall back on something else, depending on the system.
// Warning: If this is not truly steady, then it is non-conforming. It is
// better for it to not exist and have the rest of libc++ use system_clock
