2007-04-02 Joel Sherrill <joel@OARcorp.com>

	* Makefile.am, configure.ac: Convert from Classic API style TOD_Control
	as fundamental time structure to POSIX struct timespec. Add
	clock_get_uptime().
	* nsecs/.cvsignore, nsecs/Makefile.am, nsecs/init.c, nsecs/nsecs.doc,
	nsecs/nsecs.scn: New files.
