  14   *
  15   * ChangeLog:<br>
  16   *           - 1.0 initial release
  17   *           - 1.1 added support for +/- N syntax for begin
  18   *                and end year values. (Monte)
  19   *           - 1.2 added support for yyyy-mm-dd syntax for
  20   *                time value. (Jan Rosier)
  21   *           - 1.3 added support for choosing format for
  22   *                month values (Gary Loescher)
  23   *           - 1.3.1 added support for choosing format for
  24   *                day values (Marcus Bointon)
  25   *           - 1.3.2 support negative timestamps, force year
  26   *             dropdown to include given date unless explicitly set (Monte)
  27   *           - 1.3.4 fix behaviour of 0000-00-00 00:00:00 dates to match that
  28   *             of 0000-00-00 dates (cybot, boots)
