title: How do I get a list of timezone names of a browser
body: <p>I want to get the browser specific timezone names (different browsers displays different text for each system setting) for system available time zones. I need the exact string of the timezone that are in the "()" when writing console.error(new Date()) but not just for my current settings, without changing my OS settings and restarting the browser each time.</p>
  
  <p>AFAIK js libraries uses their own name lists to solve this but the resulting names are different from the browser timezone name. I need the name as the browser will write it.</p>
  
  <p>Thanks.</p>
