exchanged based time stamps, feeds that have it, software than properly handles it.

[John Bowles <johnbowles@xxxxxxxxxxxx>]

Hi All,

Are there any programs, brokers, data feeds which when brought together 
in combination can be used to get precise charts using exchange based 
time stamps (a time stamp that is applied, at the exchange, at the time 
of the trade and done properly as a result of the exchange computer 
clock being accurate as a result of regular atomic clock updates during 
the day using a program like "Dimension4" for example).
Example1 : Interactive Brokers (according to their technical people) is 
using exchange based time stamps with their feed but can the software 
that is taking their feed actually use it properly for back fill and 
real time bars too?
Example2: Qcharts (which I no longer use) was scheduled to be taking 
exchange based time stamps with the new Esignal feed. However, when 
Qcharts was being used with quote.com it was getting a random server 
time stamp and the charts would vary depending on the server feeding 
your chart at the moment. Also Quote.com was going back at night and 
making their data have matching time stamps across servers so a printout 
the next day would actually be different than a print out right after 
the market hours were over.
Put another way:
   What exchanges provide these accurate time stamps?
   What feeds have these time stamps?
   What software can use them properly?

Also, are there any charting software that report the difference between 
the exchange time stamp time and the PC clock time at the exact time of 
arrival of the tick for the purpose of alerting the trader of any 
internet delays and how large they may be. I became sensitive to this 
when, a times, Qcharts on the Quote.com feeds would actually lag by 10 
seconds to 60 seconds (an auto notification would have been nice).
Thanks,
John.
