The filter time in minutes (floating point value) when USER is specified as the filter type.
Otherwise, it is 0.0.
0.0 = no filtering (last sampled value is the input value)

Note that exceptionally large values tend to maintain the previous value whereas very
small values tend to maintain the most recent sampled value.
