It would be interesting to have more details, since that article makes a
lot of Google not using NTP and then proceeds to describe a network
protocol that sounds exactly like NTP, down to how it distributes stratum
zero clock sources to other systems in the same data center.  So it's not
clear exactly what they changed.
