Re: NSURLConnection timeoutInterval only works in multiples of 30 seconds

[Jerry Krinock]

I know that you folks have taken a different turn with this  
discussion, but I need to post my test results to finish what we  
started a couple days ago, for other readers.

RESULTS
In Tiger, it behaves as I recall and exactly as Kanny described: The  
timeout gets rounded up 30 or 60 seconds.  Bug.

In Leopard, the timeout works correctly, even down to 1 second.  Bug  
has been fixed.
