You can always use a $6k rubidium clock http://www.antelopeaudio.com/en/products/10m-atomic-clock if you really want to make sure your bits are synchronized. It's good enough for wu-tang!
For buffered data being sent and decoded, like via ethernet, the bits are the same on both ends, so I'm not sure what effect you would even make up to say it could change the output.
