title: List of major cities with latitude longitude and timezone
body: <p>I am looking for an open source flat file (comma separated values for example) of the major cities in this world, together with their latitude longitudes and timezone. The first 1000 or more is fine. Is such a resource available?</p>
  
  <p>Eventually, a combination of two flats files (lat/long &amp; timezone) is fine too.</p>
