What is the correct date format (NSDateFormatter)?

Question

I'm trying to parse this date : 2016-04-16T10:00:00-0400 but I don't know what is '-0400' in this case ?

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss<?>"];
                                                 ^^^
NSDate *date = [dateFormat dateFromString:@"2016-04-16T10:00:00-0400"];

Thanks for your help !

Read the NSDateFormatter documentation carefully. Find the link to the Unicode standard in the documentation which lists all the date formats. — gnasher729, Apr 16 '16 at 13:39

use

   NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];
//[dateFormat setLocale:[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"]];
NSDate *date = [dateFormat dateFromString:@"2016-04-16T10:00:00-0400"];
NSLog(@"date ==%@",date);
 [dateFormat setDateFormat:@"yyyy"];
NSString *finalStr = [dateFormat stringFromDate:date];
NSLog(@"finalStr ==%@",finalStr);

output like

The answer is for the date 2016-04-16T10:00:00-0400 is :

[dateFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ssZ"];
