I think you variable probably in the lat/lon projection, if the IDV can 
recognizes the time step, it should be vary easy to aggregate the time 
dimension, simply by selecting the Aggregate Grid by Time in the Data Source 
Type. Let me know if it doesn't work for you.

The reflectivity variable should be 3D: reflectivity(t, y, x), and t is the 
dimension, the nc file should also have a variable
for this time dimension, just as the x,y dimensions have their own variables, 
and the _CoordinateAxisType should be added to the time variable.
