@riyaz: If the device *time* is wrong (and not the time zone) then there is nothing you can you (apart from contacting an NTP server). — Martin R, Sep 17 '13 at 11:30

Try the below:

NSDateFormatter *dateFormatter = [NSDateFormatter new];
dateFormatter.dateFormat = @"yyyy-MM-dd'T'HH:mm";
NSTimeZone *gmtZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
[dateFormatter setTimeZone:gmtZone];
NSString *timeStamp = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"%@",timeStamp);

@RIYAZ i am also getting same problem. do you find any solution for this one? – Hari Babu Oct 14 '14 at 11:20
@HariBabu No , i also tried with ntp-ios but no luck . – Shaik Riyaz Oct 14 '14 at 12:22
Guys consider to force the user set the accurate time after setting up the application, save this value somewhere maybe NSUserDefaults, I am afraid there is no way to accomplish what you want from client side without connecting a webserves or remote time service. – Tarek Hallak Oct 15 '14 at 08:01

You must rely on an external server to achieve this. There is no built in method other than the ones for recovering the local phones time.

Here is a github project where they try to do exactly this for iOS : https://github.com/jbenet/ios-ntp
