By far the nicest and simplest DateTime picker option is http://trentrichardson.com/examples/timepicker/.

It is an extension of the jQuery UI Datepicker so it will support the same themes as well it works very much the same way, similar syntax, etc. This should be packaged with the jQuery UI imo.


@David, thanks for the recommendation! @fluid_chelsea, I've just released Any+Time(TM) version 3.x which uses jQuery instead of Prototype and has a much-improved interface, so I hope it now meets your needs:
