Hi Andrea,
the NetCDF reader return the DateRange as time Intervals indeed.
As far as I can see, is a DateRangeVisitor inside the ImageMosaic reader
which returns the temporal domain as compact time periods when it find date
ranges.
Not sure to remember why it has been set to return them as periods instead
of intervals. I vaguely remember some internal discussion about time range
validity, in order to specify that the granules of the mosaic are
continuously valid for the full extent of the interval, specifying that
with a resolution of 1 second as period, in relation to some convention of
specific services/specifications.
We may consider revisiting this behaviour if needed, with a look to the
specifications.
Hope this helps.
Daniele
