The clocks on IB's time servers are 5 seconds slower than the official us time shown here... http://www.time.gov/timezone.cgi?Eastern/d/-5/java Given how absolutely crucial timing is in this trading game can anybody else smell a big rat too? I am so pissed of about this. Its really really underhand. What I want to know is why as I was typing this the clocks went back to being the same. I just went back to check again as I was typing and now they are the same. For every layperson out there who uses I.B I suggest you check that the internal IB clock exactly matches the official US time clock since I am 100 % positive that mine was operating with a 5 second lag. There are some serious implications to this kind of time manipulation and its best you get to grips with them. This kind of manipulation is borderline criminal and Im not going to sit back and ignore it. It fucks all the timing up with my figures.
