Accurate time on iPhone

Question

Is there an way to get a time very precisely in iPhone.? Currently i am trying with the ios NTp client Here . I am getting almost 600 milliseconds difference while comparing with different divices . Even i am not worrying about the accurate time like ntp , I want to show same time with milliseconds in different devices.

Answer 2

This is simple way to do this go through it :-

 + (NSDate *) GMTNow
 { 
  NSDate *sourceDate = [NSDate date];
  NSTimeZone* currentTimeZone = [NSTimeZone localTimeZone];
  NSInteger currentGMTOffset = [currentTimeZone secondsFromGMT];

  [sourceDate dateByAddingTimeInterval:currentGMTOffset];

  return sourceDate;
  }
