should load data from two CDFs (2012-09-29 and 2012-09-30) but doesn't. I suspect there's a problem with the implementation of the code issuing the message "data trimmed from dataset to avoid overlap at Epoch=2012-09-30T00:00:03.329Z"
This was not detected because of a bug 1125.
I'm going to accept the pngwalks so I can move on with the tests, and I'll look at this later today.
The problem is that the CDF contained a record at the end of the day that was 24 hours off. This is a pretty easy mistake to make, and I'm putting in code that checks for this.
