fluttrader... thankyou for that link. That might be just the solution that I need to solve my time synching problems. Provided that IB who refuse to allow there clients to accesss THEY'RE OFFICIAL TIME and how THEY choose to interpret it and my idea of what official time is agree with each other. Otherwise the tiny differences in how I interpret official time and they interpret official time will cause how I see a chart and how they see it to be different and Ill be unable to efficiently use there system since my bars will be slightly diffferent from theyre bars. The simple solution... Make TWS official clock time synch with a generic official standard that THEY also use instead of creating an artificial difference by not allowing there customers to use theyre most valuable resource... THERE OFFICIAL interpretation of time. This whole business is based on time stamping and they wont permit there customers to synchronise with there internal clocks. Thats criminal.
