gollark: If the clocks are basically the same then this is hardly a problem.
gollark: Why? GPS-synced clocks can get accuracy within a few nanoseconds, I believe.
gollark: (Nonlinear transition permutations)
gollark: Do it nonroughly so they can all do a cycle every microsecond at around the 0ns mark or something.
gollark: Anyway, I think organisations like Google have solved the issue they're trying to address in a less insane way.
