title: Setting NSDate from NSString not working
body: <p><code>myObject.theEnd</code> and <code>myObject.theStart</code> are strings and it has the date format of <code>Thu Feb 31</code> like wise...</p>
  
  <pre><code>NSDateFormatter *format=[[NSDateFormatter alloc] init];
          [format setDateFormat:@"EEE MMM dd"]; 
          NSDate *end = [format dateFromString:myObject.theEnd];
          NSDate *start = [format dateFromString:myObject.theStart];
          NSDate *current = [NSDate date];
  </code></pre>
  
  <p>When <code>theEnd</code> is <code>Thu Feb 31</code>, <code>NSDate *end</code> shows as <code>1970-5-19 14:30 +0000</code>. It is the same with <code>NSDate *start</code> and <code>NSDate *current</code>.</p>
