When relying on indices for event binding, You must use trackBy with *ngFor

in component ts file add:

trackByIndex(index: number, item: any): number {
  return index;
}

change this in html:

   <input [timeInput]="time" (changeTime)="onTimeChanging(arrayIndex, $event)" *ngFor="let time of timeArray; index as arrayIndex; trackBy: trackByIndex">
