 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
