You could do that over very small timeframes (say, a millisecond earlier or later) but most systems don't automatically adjust times if the delta is very large

- dllthomas 13y agoA millisecond is a long time.
- maurycy 13y agoYou can make a million dollars in a millisecond.
- dllthomas 13y agoI wasn't being sarcastic.
- nonchalance 13y agoFor regulatory purposes, milliseconds are negligible. FINRA allows for up to 3 seconds of divergence from standard time sources. For deep alpha signals, a millisecond is pretty negligible (especially when you are calculating minute or 10 minute bars). For microstructure trading strategies, since the timing doesn't manipulate the book (which is where most microstructure trades derive alpha from), the effect is similarly negligible. And for cross-exchange and cross-asset arbitrage, where microseconds may seem matter (regnms), slight drifts are permissible insofar as you can plausibly argue that even if the clock is slightly off, your view of the market is internally consistent
- dllthomas 13y agoShift of the clock signal by milliseconds may well not matter, for sure, assuming all relevant clocks are affected.
