title: Scheduled messages without setInterval()
body: <p>I want to schedule some things like sending messages with my discord bot.<br>
  E.g.: I want the bot to send "Good Morning" every day at 8 am or announce some things.</p>
  
  <p>My problem is: I can't use something like <code>setInterval()</code> to execute every 24 hours because if the bot goes offline or has to be restarted it would reset or delay the interval.</p>
  
  <p>Question: How do I execute something at a specific point in time without having to worry about the bot sometimes being offline?</p>
