"datetime format for Date and Time field missing!

Yes. The kind folks at WP forced me to remove the time support because the javascript plugin that I dissected used a creative commons license. In my opinion, I had edited (read: fixed the bad code) to such a degree that the original code was no longer recognizable, but you can’t argue with the “license police” at WP. Sorry for the inconvenience. Once I find a good time-picker plugin that meets my standards and has a viable license (e.g. GPLv2), then I can revisit this issue.
