nb-date-timepicker 在 nb-datepicker 工作的地方不起作用

Question

我正在粘贴以下代码片段，其中 nb-datepicker 正在工作，但我希望时间也成为我输入文件的一部分，然后我使用了 nb-date-timepicker，但它不起作用

如果您也遇到 nb-date-timepicker 的问题，有人可以帮助我吗

<div class="col-md-6">
    <div class="row">
        <div class="col-md-6 form-group">
            <input class="dippam" placeholder="Pick From Date" [nbDatepicker]="formcontrol" formControlName="fromDate">
            <nb-date-timepicker #formcontrol singleColumn [step]="10" (dateChange)="getFromDate($event)"></nb-date-timepicker>
            <span *ngIf="f.fromDate.errors && (f.fromDate.touched || submitted)" style="color: red;">From Date is required</span>
        </div>
        <div class="col-md-6 form-group">
            <input class="dippam" placeholder="Pick To Date" [nbDatepicker]="ngmodel" formControlName="toDate">
            <nb-datepicker #ngmodel (dateChange)="getToDate($event)"></nb-datepicker>
            <span *ngIf="f.toDate.errors && (f.toDate.touched || submitted)" style="color: red;">To Date is required</span>
        </div>
        <!-- <input nbInput placeholder="Pick Date" [nbDatepicker]="dateTimePicker">
            <nb-date-timepicker withSeconds #dateTimePicker></nb-date-timepicker> -->
    </div>
</div>
