title: convert RSS pubDate to SQLite date format iPhonne
body: <p><br>
  I'm trying to build a RSS reader, but I'm having trouble with saving the date to CoreData.  </p>
  
  <pre>
  NSDateFormatter *df = [[NSDateFormatter alloc] init];
      [df setDateFormat:@"yyyy-MM-dd"];
      NSDate *dt = [df dateFromString: [article valueForKey:@"pubDate"]];
      [df release];
  </pre>
  
  <p>When I save everything, the date field in the database is null.<br>
  Please help!</p>
