I tried a simple NcML aggregation along time for a few 12-km NAM
files, downloaded from motherlode via the NetCDF subset server. The
forecasts are updated every 6 hours, and each forecast has a different
time origin. Does NetCDF-Java only look at the first time origin when
I was trying to create a "best wind" time series by taking only
forecast hours 3 and 6 from each 72 hour forecast. If I load the
files using NetCDF-Java, the times are correct, with a uniform time
interval of 3 hours. But when I look at the aggregation, the first
two time values get repeated for the duration of the time series.
The .nc files and .ncml file are in this zip:

Is this a bug, and if so, is there a workaround?
