Time picker is misbehaving #3415

#### Summary

_"It is not possible to enter a time after 11:59 AM. The dropdowns appear to support 
24-hour time entry, but they do not. If a time greater than 12 is entered, 12 hours are subtracted from the selection."_

The configuration for the `datetimepicker` was incorrect. Simple two-character change.

_"The time picker does not submit on change. It seems to be possible to enter a time that is not saved at all."_

Reverted a change that made the `datetimepicker` update `onblur`. Now the `datetimepicker` posts when a change is made via the dropdowns and when "done" is clicked.
