title: How to get the common name for a pytz timezone eg. EST/EDT for America/New_York
body: <p>Given a pytz timezone for a particular user(calculated from his offset), i want to display the common name for that timezone. I'm assuming people are more accustomed to seeing <strong>EST</strong> or <strong>PST</strong> instead of spelled out like <strong>America/NewYork</strong>.</p>
  
  <p>Does pytz give me those standard names somewhere, or will i have to manually do this via a table? This could potentially get messy, since for example places are EST in a season and shift to showing EDT during others.</p>
