title: NSDateFormatter and Time Zone issue?
body: <p>I have a string with time in GMT and i want to make it according to the system time zone but its not working properly -</p>
  
  <pre><code>NSLog(@"Time Str = %@",Time);
  
  NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
  [dateFormat setDateFormat:@"dd-MM-yyyy hh:mm a"];
  
  [NSTimeZone resetSystemTimeZone];
  
  NSLog(@"system time zone = %@",[NSTimeZone systemTimeZone]);
  
  [dateFormat setTimeZone:[NSTimeZone systemTimeZone]];
  
  NSDate *date = [dateFormat dateFromString:Time];
  
  [dateFormat setTimeZone:[NSTimeZone systemTimeZone]];
  NSLog(@"date from string = %@",date);
  NSLog(@"string from date = %@",[dateFormat stringFromDate:date]);
  </code></pre>
  
  <p>Output at console - </p>
  
  <p>////////////////////////////////////////////////////////////////////////////////////////////////</p>
  
  <p>Time Str = 09-12-2011 07:57 AM</p>
  
  <p>system time zone = Asia/Calcutta (IST) offset 19800</p>
  
  <p>date from string = 2011-12-09 02:27:00 +0000</p>
  
  <p>string from date = 09-12-2011 07:57 AM</p>
  
  <p>////////////////////////////////////////////////////////////////////////////////////////////////</p>
  
  <p>Calcutta is +5:30 from GMT, so the time in date should be 1:27 but its showing 02:27. Also when i take a string from this date its showing me the same sting that i used to make date, i want the string updated according system time zone. </p>
  
  <p>Thanks</p>
