title: setting date format for NSDateFormatter
body: <p>I am trying to set the date format for something like "2011-04-21 03:31:37.310396". I think I'm not getting the fractional seconds right.  I'm looking at <a href="http://unicode.org/reports/tr35/tr35-10.html#Date_Format_Patterns" rel="noreferrer">http://unicode.org/reports/tr35/tr35-10.html#Date_Format_Patterns</a> for guidelines on how to specify it and I think my issue is in the format itself.</p>
  
  <pre><code>NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
  dateFormatter.dateFormat = @"yyyy-MM-dd HH:mm:ssSSSSSS";     
  NSDate* serverDate = [dateFormatter dateFromString:stringFormOfDate];    
  </code></pre>
  
  <p>Help?</p>
