Get ready for 10 AM with the RxJS timer function

I am trying to figure out how to schedule a method in my code using rxjs/timer. Specifically, I want the method to run at precisely 10 AM after an initial delay of 1 minute. However, my current implementation is running every 2 minutes after a 1-minute delay. This is not the desired functionality. Can anyone provide guidance on achieving the desired behavior or suggest an alternative approach?

import { timer } from 'rxjs/observable/timer';

timer(60000, 120000).subscribe(val => {//schedule Notification
    myMethod();
});

javascript angular typescript rxjs observable

One way to achieve this is by running a timer every minute and triggering an action once it reaches 10am. Here's an example:

import { timer } from 'rxjs/observable/timer';

firstRunExecuted:boolean = false;

timer(60000).subscribe(val => {//schedule Notification
   if(!this.firstRunExecuted)
   {
      myMethod();
      this.firstRunExecuted = true;
   }
   else if(checkIfIts10AM())
      myMethod();
});

OP's feedback

timer(60000, 60000).subscribe(val => {//schedule Notification
          const hours = moment().format("H");
          if (hours == '10') this.scheduleNotification();
   });
