 *              and end year values. (Monte)
 *            - 1.2 added support for yyyy-mm-dd syntax for
 *              time value. (Jan Rosier)
 *            - 1.3 added support for choosing format for
 *              month values (Gary Loescher)
 *            - 1.3.1 added support for choosing format for
 *              day values (Marcus Bointon)
 *            - 1.3.2 support negative timestamps, force year
 *              dropdown to include given date unless explicitly set (Monte)
 *            - 1.3.4 fix behaviour of 0000-00-00 00:00:00 dates to match that
 *              of 0000-00-00 dates (cybot, boots)
 *            - 2.0 complete rewrite for performance,
