And I try to make it easy on the level2 servers (most distro naintained "pool.ntp.org" site that supply the net since I have 5 or 6 machines running mostly 24/7, I've configured my router to rebroadcast on my local, not accessable home network. So that makes this router a level 17 server and all the rest of my boxes get time well wihin 5 milliseconds of ntp. But to the level2 servers in the typical pool, I am just one client. Since its a free service but they still have to pay for the bandwidth, and electricity to run them, it makes sense to cut the bytes used if you can.
