Even though it was showing only one time for multiple files, it was really 
loading all times.  With the latest nightly build, you should see all the times 
(and be able to subset them) and if there are multiple files, you'll see the 
DataSource name as Trajectory Soundings.

We're still working on this.  Getting closer, but there's still some problem.

It's not finalized, but we might be able to fudge the existing format.

BTW, if you use relative times for the point data with ADDE, you can go back 
across the date boundary.  It's just that for the absolute times, we just use 
the current day.
