The focus issue seems to be fixed by calling
UseAltPopupWindow() before calling
SetPopupControl(m_popup);
Edit
FWIW, I tried to implement very simple combined date and time picker, similar to that in the original post. Seems to work as expected on Windows 10 (except when I use <Alt+PrtScr> to screenshot, only the pop-up and not the whole frame are captured). Probably the only important thing missing is closing the pop-up after pressing <Enter>.
