Provide the same look-and-feel of Bootstrap popover?

Strongly hope the this great date-time picker can provide the same matching look-and-feel of the official Bootstrap popover. I am using both date-time picker and popover for some inputs in the page, and the styles just do not match.

Currently I am modifying the CSS by myself, but can not get a perfect result, especially the arrow position and size.

Maybe the date-time picker can be wrapped in a popover, instead of a customized widget.
