title: send a notification one hour prior to appointment in laravel
body: <p>In my application, I am trying to do something like this, </p>
  
  <p>When a meeting is scheduled, a mail is sent out with the details. This is working already. </p>
  
  <p>Addition to this, I would also like to send out a mail and message prior to one hour before the meeting. </p>
  
  <p>How can I do this?</p>
  
  <p>Should I calculate the time from meeting_scheduled_time when the meeting details are saved and then maybe set a cron on schedule? I am not able to see a approach to do this, efficiently.</p>
