I was IPLing a system the other day and tried to call the US Naval Observatory Master Clock telephone number that we've used for years as the accurate time source for our systems. The number we used had been disconnected! A quick search of the web turned up a very good website at http://tycho.usno.navy.mil/time.html complete with phone numbers. Lots of good information on time-keeping, clocks, etc and good resources for adding various clocks to web pages. Thought it a good enough resource for systems folks to recommend it to these lists. -- Glenn A.
