title: How do you get the local timezone based on core location coordinates?
body: <p>Is it possible in cocoa touch to get the local timezone of device based on the coordinates from the gps?  I saw this asked last year, but no answer...</p>
  
  <p>All I really want is the number of hours difference from GMT, and I don't want to query a web service.</p>
  
  <p>Or, can I ask the device what timezone it is set to?</p>
  
  <p>Can it be done?</p>
