hello having same problem i've had

the solution in case quite simple (after having searched 3 days...)

<b.date:datetimepicker stylename="btn-block form-control"     b:id="dtptoid" ui:field="dtpto" format="dd.mm.yyyy"     minview="month" maxview="year" autoclose="true"     haskeyboardnavigation="true" highlighttoday="true" /> 

just add form-control stylename attribute of datetimepicker , enjoy arrows.

hope helps someone!
