+	    On Linux systems using heart (erl -heart) and a
+	    HEAR_BEAT_TIMEOUT less than default, heart could fire
+	    even though Erlang was running fine after approx 298 to
+	    497 days (depending on kernel config). This was due to
+	    the behaviour of the times(2) system call. Usage of
+	    times(2) is now replaced with clock_gettime(2) and the
+	    CLOCK_MONOTONIC clock, resulting in a more stable
+	    solution. The Erlang VM itself has used clock_gettime(2)
+	    on linux since before R12B, so this only affects the
+	    heart program.</p>
