title: Set min time to ngb-timepicker Angular 4
body: <p>I implemented a really simple form to choose a range of time as the one in the code below:</p>
  
  <pre><code>&lt;form [formGroup]="editEventForm" (ngSubmit)="c(onSubmitUpdate())"&gt;
    &lt;div class="form-group bottom-form-details"&gt;
      &lt;div class="row"&gt;
        &lt;div class="col-sm-6"&gt;
          &lt;label class="labels-status-form"&gt;Start Time&lt;/label&gt;
        &lt;/div&gt;
        &lt;div class="col-sm-6"&gt;
          &lt;ngb-timepicker [(ngModel)]="startTime" formControlName="startTime"&gt;&lt;/ngb-timepicker&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="form-group bottom-form-details"&gt;
      &lt;div class="row"&gt;
        &lt;div class="col-sm-6"&gt;
          &lt;label class="labels-status-form"&gt;End Time&lt;/label&gt;
        &lt;/div&gt;
        &lt;div class="col-sm-6"&gt;
          &lt;ngb-timepicker [(ngModel)]="endTime" formControlName="endTime"&gt;&lt;/ngb-timepicker&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="modal-footer"&gt;
      &lt;button type="submit" class="btn btn-primary btn-5"&gt;Update&lt;/button&gt;
      &lt;button type="button" class="btn btn-outline-dark" (click)="c('Close click')"&gt;Close&lt;/button&gt;
    &lt;/div&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>The models <strong>startTime</strong> and <strong>endTime</strong> just get the current hour and the current minute.</p>
  
  <p>Once I set the start time(hour and minutes) through ngb-timepicker I would like to set end time from the start time. i.e. if I set 05:30 as start time I would like to set end time from 05:31.</p>
  
  <p><strong>ngb-datepicker</strong> provides a <strong>[minDate]</strong> but it is not the case with <strong>ngb-timepicker</strong>.
  Is there any way to do that in Angular 4?</p>
  
  <p>Thanks in advance.</p>
