Added to Docker example as Swarm mode likes time sync. Note uses pool.ntp.org at present, on some providers it should use a different source. Constraints not enabled as they seem to have an issue; possibly trying to set before network is up. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
