* - 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)
