title: Fix date to specific timezone in ng-pick-datetime
body: <p>I have an ng-pick-datetime control and I want show all dates in the Europe/London timezone.  My dates are coming from the server as UTC.</p>
  
  <p>e.g. I am in New Zealand and I want to see the dates as local London time as I want to make a booking in London time.  Currently they are showing in New Zealand time.</p>
  
  <pre><code>&lt;input 
    class="shadow-input" 
    type="hidden" 
    [(ngModel)]="booking.bookingDate" 
    [owlDateTime]="dt" 
    [min]="minBookingDate" 
    [max]="maxBookingDate"&gt; 
  
  &lt;owl-date-time [pickerMode]="'dialog'" #dt&gt;&lt;/owl-date-time&gt;
  
  &lt;input 
    type="text" 
    class="form-control pl-2 input-custom input-postpend"
    [owlDateTimeTrigger]="dt" 
    placeholder="Select Date"
    (focus)="onDateInputClick($event)" 
    (click)="onDateInputClick($event)"
    [min]="minBookingDate" 
    [max]="maxBookingDate" 
    [readonly]="booking.bookingDate"  
    [value]="booking.bookingDate | dateFilter: dateFormat"&gt;
  </code></pre>
  
  <p>Note: I also asked if I could change the timezone application wide but I haven't been able to figure that out. <a href="https://stackoverflow.com/questions/57102497/setting-global-timezone-in-angular">Setting global timezone in Angular</a></p>
