title: JSON date string conversion issue in iOs
body: <p>I am getting some UTC date strings from WCF Rest service and here is the format:</p>
  
  <pre><code>/Date(1354851639500+0530)/
  </code></pre>
  
  <p>I used the following code to convert the date:</p>
  
  <pre><code>//jsonDateString = 1354851639500+0530
  
  NSInteger offset = [[NSTimeZone defaultTimeZone] secondsFromGMT]; //get number of seconds to add or subtract according to the client default time zone
  
  NSTimeInterval unixTime = [[jsonDateString substringWithRange:NSMakeRange(0, 13)] doubleValue] / 1000; //WCF will send 13 digit-long value for the time interval since 1970 (millisecond precision) whereas iOS works with 10 digit-long values (second precision), hence the divide by 1000
  
  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"];
  [dateFormatter setTimeZone:timeZone];
  [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss a ZZZZ"];
  NSString *stringFromDAte = [dateFormatter stringFromDate:[[NSDate dateWithTimeIntervalSince1970:unixTime] dateByAddingTimeInterval:offset]];
  NSLog(@"Server GMT: %@", stringFromDAte);
  
  
  NSDate *currentDadte = [dateFormatter dateFromString:stringFromDAte];
  NSTimeInterval interval = [currentDadte timeIntervalSinceDate:[NSDate date]];
  
  return [self dailyLanguage:interval];
  </code></pre>
  
  <p>But when I convert the time is not correct. I need to get the UTC time of the receiving time. But I am getting the time value without the offset value. </p>
  
  <p>For example: if josnDate = 1354851639500+0530,
  i am getting,  2012-12-07 03:40:39 AM GMT, but i should get 2012-12-07 09:10:39 (approx).</p>
  
  <p>How can I do this? Please help.</p>
