Any GPS clock you are going to find in NY4 is going to be sufficiently sophisticated to check the GPS signal against its internal oscillator in order to check for validity. It can fall back to the internal oscillator if the GPS time looks bad.
The other reason this is unlikely to be a problem is that network time protocols break all the time (oops someone did a maintenance and broke sync with the master clock). Lots of real world trading code has sanity checks on the time.
- atemerev 10y agoThis is why I mentioned a spoofer, not jammer :)
- minimax 10y agoIt's the same problem. Assume my GPS clock is synced to actual GPS. You turn on your spoofer and now my clock sees that the GPS source is running faster or slower than it should be so it falls back to the internal oscillator.
