title: Set a timer on 10 AM Rxjs/timer
body: <p>Could you tell me how can I use <code>rxjs/timer</code> to run a method on exact time? I would like to have an initial delay as <code>1 min</code> and after that, it should run at <code>10 AM</code> like so. But I was not able to do that. I have done like below. But it fires every 2 mins after 1 min delay. But I need as mentioned above functionality. Any clue or can you tell me another approach maybe?</p>
  
  <pre><code>import { timer } from 'rxjs/observable/timer';
  
    timer(60000, 120000).subscribe(val =&gt; {//schedule Notification
              myMethod();
        });
  </code></pre>
