NTP, an atomic clock, and having a great time at the world's largest VCF

I'm back from VCF Midwest 21, arguably the largest vintage computer festival on the planet. After being blown away last year, I decided to get a table of my own this year, to demonstrate NTP Time on a bunch of old Macs, representing every era up to the pinnacle of the PowerPC, an Xserve G5 (serving duty as a Stratum 2 ntpd server). Attending as an exhibitor is a lot different. In some ways better (I got to interact face-to-face with at least 200 people—after that I ran out of my 'time tokens'), and in some ways worse (I only got to see about 10% of the exhibits—if that).
