Для этого существует открытая проблема в качестве запроса функции: https://github.com/ng-bootstrap/ng-bootstrap/issues/2086
DatePicker и TimePicker можно комбинировать с некоторым пользовательским кодом. 
Вот пример, который использует ввод текста с помощью кнопки для открытия средства выбора даты и переключения между средством выбора времени.
HTML:
<div class="input-group mr-2">
<input
[ngClass]="ngControl?.valid ? 'ng-valid' : 'ng-invalid'"
class="form-control"
(blur)="inputBlur($event)"
[ngModel]="dateString | date:inputDatetimeFormat"
(change)="onInputChange($event)"
[disabled]="disabled"
/>
<div class="input-group-append">
<button
class="btn btn-outline-secondary"
[ngbPopover]="calendarContent"
[disabled]="disabled"
type="button"
>
<fa-icon [icon]="['far', 'calendar']"></fa-icon>
</button>
</div>
</div>
<ng-template #calendarContent>
