public class NumericToDate extends SimpleBatchFilter implements WeightedAttributesHandler, WeightedInstancesHandler
A filter for turning numeric attributes into date attributes. The numeric value is assumed to be the number of milliseconds since January 1, 1970, 00:00:00 GMT, corresponding to the given date." Valid options are:-R <col1,col2-col4,...> Specifies list of attributes to turn into date ones. Only numeric attributes will be converted. First and last are valid indexes. (default: first-last)
-V Invert matching sense of column indexes.
-F <value index> Sets the output date format string (default corresponds to ISO-8601).
