title: Google Maps API v3 Places Library returning undefined utc_offset
body: <p>I'm developing a time and location aware application and the google maps v3 api places library has almost everything I need.  However, when doing a textSearch() for specific addresses, and attempting to call getDetails() for one of the returned PlaceResult items, the PlaceResult.utc_offset property returned from getDetails() is undefined (all the other PlaceResult properties I need are returned fine, just not the utc_offset).  </p>
  
  <p>It's strange, because if I do a textSearch() for a generic term like "pizza" and then call getDetails() for one of the returned PlaceResult items, the PlaceResult.utc_offset property returned from getDetails() will have a value.</p>
  
  <p>Does anyone know why the utc_offset is populated for the results of a generic search, but not when searching for a specific address, or what am I doing wrong?</p>
