Yes.

I presume that comes from your edit mask, you should just be able to
type the time in using the defined mask. If you want to use the mouse
make sure that DateOptions.dtoShowTime is ticked and there will be
some time spinedits on the dropdown.

When dtoShowTime is true then clicking the Now button on the dropdown
should set the value to the current datetime. (When false it only
sets the date.)
