title: Refresh Angular component similar to Cron job
body: <p>I have a Dashboard component in my Angular 6 application which I need to refresh every clock minute as the data that am fetching from API gets updated every minute (There is a Cron job running on backed to update the data).</p>
  
  <p>I know about <code>Observable.interval(60000)</code> but it would be my last option to use as my API data gets refreshed after every minute in the clock and not on 60 sec interval.</p>
  
  <p>For e.g. Say App starts at 8h 0 min and 30 sec AM. I don't want my dashboard to refresh after 60 sec i.e 8h 1 min and 30 sec but I want it to refresh on 8h 1 min and 0 sec. Hope what am asking for is clear.</p>
