WebNCL's filter functions operate over discrete time steps in a time series. Their time metric is time steps, *not* calendar time or real time. This is a common point of confusion about digital filters. Therefore, the filters *do not care* about your time units or time coordinate variable. To get correct filter parameters, you must manually (or ...
