title: Can I set the local timezone in my browser via Javascript?
body: <p>I know I can get the local timezone offset via new Date().getTimeZoneOffset().  But where did Javascript get that information?  Is there a way I can set it, so that all future Date objects have the offset I want?  I tried searching the DOM in Firebug, but couldn't find anything.  </p>
  
  <p>What I am trying to accomplish is converting epoch times to readable format, but it needs to be in US/Central, no matter what the browser's OS setting.  Because I am using US/Central, it's not a fixed difference from GMT.  So instead of a bunch of super nasty conversion steps, why can't I just tell Javascript that I'm actually in US/Central?</p>
