title: How to convert my server time to other country time?
body: <p>I am getting time from server is <code>2016/07/19--12:20:00</code>
  Now I have to change this time according to country.
  For example If I am in Auckland then time has to like <code>2016/07/19--18:50:00</code>
  I found so many solutions in stack overflow but I can't solve this.
  Please help me</p>
  
  <pre><code> NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
          [dateFormatter setDateFormat:@"YYYY/MM/dd--HH:mm:ss"];
          NSDate* sourceDate = [dateFormatter dateFromString:model.tripEndTime];
          NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
          NSTimeZone* destinationTimeZone = [NSTimeZone localTimeZone];
          NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:sourceDate];
          NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate];
          NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;
          NSDate* destinationDate = [[NSDate alloc] initWithTimeInterval:interval sinceDate:sourceDate];
          NSDateFormatter* dateFormat = [[NSDateFormatter alloc] init];
          [dateFormat setTimeZone:[NSTimeZone systemTimeZone]];
          [dateFormat setDateFormat:@"YYYY/MM/dd--HH:mm:ss"];
          NSString* localTime = [dateFormat stringFromDate:destinationDate];
          NSLog(@"localTime:%@", localTime);
  </code></pre>
