time.h: Add CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID definition
see the spec here:
#define CLOCK_MONOTONIC 1
+/* Clock that measures CPU time consumed by this process (i.e., CPU
+ * time consumed by all threads in the process).
+ */
+
+#define CLOCK_PROCESS_CPUTIME_ID 2
+
+/* Clock that measures CPU time consumed by this thread */
+
+#define CLOCK_THREAD_CPUTIME_ID 3
+
/* Monotonic system-wide clock that includes time spent in suspension. */
-#define CLOCK_BOOTTIME 2
+#define CLOCK_BOOTTIME 4
/* This is a flag that may be passed to the timer_settime() and
* clock_nanosleep() functions.
