title: How are user's timezone encoded in facebook
body: <p>I need to check user's time zone... but I can't find how it defined really.<br>
  <a href="http://developers.facebook.com/docs/reference/api/user/" rel="nofollow">The reference API</a> says : <em>The user's timezone offset from UTC</em></p>
  
  <p>Now on Wikipedia these are the <a href="http://en.wikipedia.org/wiki/Time_zone#Time_zone_as_offsets_from_UTC" rel="nofollow">timezone possible</a>.<br>
  Take India as an example :  UTC+05:30.</p>
  
  <p>So <strong>how does facebook encode</strong> this in users's field <strong>timezone</strong>.<br>
  Since I'm in Europe my own timezone is : 2, actually it should be 1 but I presume the summer time is build in. Howerver I don't know for sure.</p>
