Great link! I hadn't seen it before. ntp.org is definitely over-complicated -- they're trying to "tell you how to build a watch, when all you asked for was the correct time". (
sorry, couldn't resist.)

Some notes: (from memory... mine)
The norm for ntp is to check the time every 1024 sec. (17.066... min.) after stabilizing. This is acceptable; however, it is considered abusive to have a non-server check this often, 1 to 3 times per day being recommended (if I remember correctly). The rule of thumb is, as soon as you have 3 boxen needing time sync, you should set up your own server & sync your LAN to that.
Rules of Engagement
! (And follow them.)
If you use the server list, Stratum Two Time Servers
(please don't touch the ones in Stratum 1), please pay attention to the "AccessPolicy:" & "Notify?" fields.
Consider the pools: NTP Pool Time Servers
; as well as your own ISP, who really ought to be supplying you with a time server.
I used to know some tricks to track down my ISP's server, but it's been so long ago I've forgotten, sorry.

FWIW, my 500th post.
