Google decided a few years ago to skip all leap seconds by implementing 
their own leap smear hack to a DMZ ntp server that bridges the gap 
between normal NTP servers and the internal "la, la, la, la, la, I can't 
hear you!" world which tries hard to avoid having to care about steps in 
UTC seconds counting.
