The atomic clock bit isn't novel at all. I've worked for HFT firms the past 9ish years and using hardware timesources is 101 level intro to electronic trading.

- kasey_junk 10y agoBut atomic ones? We used ptp or gps for this sort of work but I don't know that I've seen an atomic clock.
- scottlocklin 10y agoThe actual patent talks a lot about NIST GPS clocks, and not so much about atomic clocks. Never trust a headline. Gell Mann Amnesia Effect in full play here.
- SEJeff 10y agoSure. You can't get roof access (for a gps antenna) or a vendor ptp feed in every exchange. In those places, you get a rubidium decay stratum 0 timesource. Not all businesses can afford this, but it is only 4 or 5x the price of a normal GPS timesource, which is affordable for the right people.
