The NTP pool guys have set up our vendor domain. I'd like to commit
the patch below to ntp.conf. It does the following:

	1) Uses our vendor domain at the pool.
	2) Points people at the pool website and encourages
	   people to provide a server in the pool (as a
	   courtesy to the pool guys).
	3) Fixes a spelling.
	4) Comments out the local clock and includes a link
	   to documentation for use of the local clock on
	   the ntp.org site.

If there are no objections, I'll ask re@ for permission to commit
this.

	David.
