Configure the NZ date picker time selection component of ng zerro

1、 The official sample nz-date-picker

​ The effect achieved in the official example cannot meet the requirements of business query , such as : I need to select the start time first , Then when you select the end time, you cannot select the data of the same date , And even if you choose “ At the moment ” when , The corresponding time is not disabled

​ explain :ng-zerro There is a corresponding implementation , But in the example, it's relatively simple , It's not going to work , This paper only makes its own implementation record
file

2、 How to achieve can choose the same time , And disable the time that is not in the selected time range

​ Such as : Starting time 2020-11-09 12:12:12, The end time needs to be selected 2020-11-09 12:12:12, And less than 2020-11-09 12:12:12 Time to disable

html Realization :

                                    <nz-date-picker
                    [nzDisabledTime]="disabledStartTime"
                    [nzDisabledDate]="disabledStartDate"
                    nzShowTime
                    nzFormat="yyyy-MM-dd HH:mm:ss"
                    [(ngModel)]="startValue"
                    nzPlaceHolder=" Starting time "
                    (ngModelChange)="onStartChange($event)"
                  >
                  </nz-date-picker>
                  <nz-date-picker
                    [nzDisabledTime]="disabledEndTime"
                    [nzDisabledDate]="disabledEndDate"
                    nzShowTime
                    nzFormat="yyyy-MM-dd HH:mm:ss"
                    [(ngModel)]="endValue"
                    nzPlaceHolder=" End time "
                    (ngModelChange)="onEndChange($event)"
                  >
                  </nz-date-picker>
