public class ChangeDateFormat
extends Filter
implements UnsupervisedFilter, StreamableFilter, OptionHandler
Changes the date format used by a date attribute. This is most useful for converting to a format with less precision, for example, from an absolute date to day of year, etc. This changes the format string, and changes the date values to those that would be parsed by the new format.
Valid options are:
-C <col> Sets the attribute index (default last).
-F <value index> Sets the output date format string (default corresponds to ISO-8601).
