Hi Jeff - I must have not been clear in my latest post in this thread -
sincere apologies for that. When I said 'I am told there is a bug on IB's
end' I meant IB = Interactive Brokers and not IBrokers. Sorry for the
confusion. This is something internal to Interactive Brokers so nothing to
do with the IBrokers R package.

I'm not sure what you are trying to say in the above paragraph.

I agree that this has nothing to do with an R solution hence why I posted an
update indicating that the problem occurs with Interactive Broker's own
tools:

1) the time issue is not present when you use TswDde, however it is present
when you use TswActiveX. The first 1 minute intraday bar occurs at 09:30:00
and the last bar at 15:59:00 when you export historical data using
tswActiveX. The same does not occur when you use TswDde. 

2) the missing data issue occurs with both TswDde and TswActiveX. 

I thought that issue #2 may have had to do with 'poor quality' data rather
than a problem with the export mechanism. But Interactive Brokers technical
support rep I was working with indicated on several occasions that he did
not have missing data during his testing using the same said tools for the
same time periods and same symbol. Now this is his *claim* and not something
that I can independently verify other than indicate that there are gaps in
the data exported from Interactive Brokers using their tools in my testing.

All the best.
