title: Getting the Time Zone (just the timezone) using angular
body: <p>I'm not sure if this is possible, but I want to get the PC's Time Zone using Angular. I just need the timezone because I need to format it in ('+H:MM').</p>
  
  <p>I understand Angular only formats it one way ('+HHMM'), so I want to store this Time Zone and put in a string that I can then manipulate later.</p>
  
  <p>Also I don't want to use plugins and/or libraries, if possible.</p>
