From c339d6843e3104e75c9a378da7be50dc9353e777 Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>
Date: Mon, 21 Feb 2005 08:14:40 +0000
Subject: Include gethrxtime.h, xtime.h. (start_time): Now of type xtime_t, not
 struct timespec. (print_stats, main): Use gethrxtime rather than gettime.
