Having gone through this a few times myself, is there a way in the
RequestInformation to get the Time information from the file? On some
of my custom files that involved opening the file to do a partial read
just to get the time information (and a few other pieces of
information) for the pipeline.
I have some source code that you can look at if you need it.

Seems that was the final issue. I was initializing those variables
in RequestData, but RequestInformation is called before then. I
wound up simply making RequestInformation call RequestData, and now
it works! :)

Uhhhh... I dunno. It should report all of the time steps. Are you
sure
your RequestInformation method is reporting all of the time steps,
and not
just 2?
