title: Unable to save correct Date using CoreData
body: <p>I created a CoreData application using the Cocoa Touch Template. I modified the included .xcdatamodel file to have an attribute called 'Date' with datatype of 'Date' and other string attributes.</p>
  
  <p>I use following codes to save data for the 'Date' field:</p>
  
  <pre><code>NSDateFormatter *dateFormatter=[[[NSDateFormatter alloc] init] autorelease] ;
  [dateFormatter setDateFormat:@"YYYY-MM-DD"];
  NSDate *date= [[[NSDate alloc] init] autorelease];
  date=[dateFormatter dateFromString:@"2010-03-01"];
  
  [newManagedObject setValue:date forKey:@"Date"];
  
   NSError *error;
      if (![context save:&amp;error]) {
          // Handle the error...
      }
  </code></pre>
  
  <p>To show the data in TableView I write following code in cellForRowAtIndexPath: method:</p>
  
  <pre><code>// Configure the cell.
  
  NSManagedObject *managedObject = [fetchedResultsController objectAtIndexPath:indexPath];
  
  //Formatting Date Portion of Name
  NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init]  autorelease];
  [dateFormatter setDateFormat:@"DD MMM YYYY"]; 
  
  NSString *fName= [NSString stringWithFormat: @"%@: %@", [dateFormatter stringFromDate:[managedObject valueForKey:@"Date"]],[[managedObject valueForKey:@"Name"] description]];
  </code></pre>
  
  <p>I am really surprised that cell in TableView shows - 01 Jan 1970: Test</p>
  
  <p>I also tried to use NSDateComponents instead of NSDateFormatter so I changed the code for saving date with:</p>
  
  <pre><code>    NSDateComponents *comps = [[NSDateComponents alloc] init];
  [comps setDay:1];
  [comps setMonth:3];
  [comps setYear:2010];
  NSCalendar *gregorian = [[NSCalendar alloc]
                           initWithCalendarIdentifier:NSGregorianCalendar];
  NSDate *date = [gregorian dateFromComponents:comps];
  [comps release]; 
  </code></pre>
  
  <p>This time surprisingly cell displayed - 60 Mar 2010.</p>
  
  <p>So I get 2 different but wrong values, but am unable to show the correct value which should be - 01 Mar 2010. I am really at loss of ideas on what could be going wrong here. </p>
  
  <p>Can anybody suggest me where can I begin looking? Is there anything wrong with my code? Are there some well recognised issues with saving dates using CoreData?</p>
  
  <p>Looking forward to your replies. Thanks in advance. </p>
