It is currently not possible to select time.

It woulb be great to be able to select the time too, since Eonasdan/bootstrap-datetimepicker allow to do this. But, the pickTime option of datetimepicker is set to false and not configurable :

      return input.datetimepicker({
          language: language,
          pickTime: false,
       ....
