pool is normally a round robin server setup where any machine in
the "pool" of machines can answer the query. Its part of the net
address, not a keyword to ntp(date). If you ping -c1 pool.ntp.org,
you'll see the machines address that answered that ping, but you may not
get a reply from that same machine the next time you ping it.
