title: Using momentJS to get the time today at a certain string
body: <p>So basically if I have a string <code>'8:00 PM'</code>, I want to get a moment object for today's date at 8PM.</p>
  
  <p>Obviously, <code>moment('8:00 PM')</code> won't do it.  I've also tried to use <code>moment().startOf('day')</code>, but I'm not sure how to get it set to 8PM.  It has to be from a string or I would be able to add hours or minutes to get the time I need.  Thanks.</p>
