Any time you're looking at network protocols, the one obvious place to
look is the RFCs. Just do a web search for 'rfc ntp' to find the
relevant ones. In my case, the search results pulled up a couple of
good-looking hits from ietf.org (the Internet Engineering Task Force -
those guys are the authority on this sort of matter), plus the
Wikipedia article for NTP, with a section "Relevant RFCs", which would
make good reading.

Enjoy! Networking's awesome fun.
