Dateformatter gives wrong time on conversation

Question

I am trying to convert my date string to NSDate but its return correct date and wrong time.

This is my code :

    NSString *dateStr = @"2013-12-20 12:10:40";

    // Convert string to date object
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
    NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];

    NSLog(@"lastUpdatedate : %@",lastUpdatedate);

It returns this :

lastUpdatedate : 2013-12-20 06:40:40 +0000

then will suggest you to convert your date into string and check log... — Leena, Dec 23 '13 at 06:31

- [NSDate description] (which is called when passing it to NSLog) always prints the date object in GMT timezone, not your local timezone. If you want an accurate string representation of the date, use a date formatter to create a correct string according to your timezone.

As @Leo Natan said, - [NSDate description] always gives date in GMT timezone. If you want to convert into local timezone then use following code.

NSString *dateStr = @"2013-12-20 12:10:40";

// Convert string to date object
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];

NSLog(@"lastUpdatedate : %@",[self getLocalTime:lastUpdatedate]);



-(NSDate *) getLocalTime:(NSDate *)date {
    NSTimeZone *tz = [NSTimeZone defaultTimeZone];
    NSInteger seconds = [tz secondsFromGMTForDate: date];
    return [NSDate dateWithTimeInterval: seconds sinceDate: date];
}

OUTPUT:

lastUpdatedate : 2013-12-20 12:10:40 +0000

How to get only 12:10:40 (Not the whole date like 2013-12-20 12:10:40 +0000) and in 24 hours format? – Natasha Jan 15 '16 at 18:30
@natasha HH:mm:ss will gives data format in 24hrs and hh:mm:ss will gives data format in 12 hrs – MilanPanchal Jan 16 '16 at 14:20

NSString *dateStr = @"2013-12-20 12:10:40";
NSDateFormatter *dateFormatterTest = [[NSDateFormatter alloc] init];
[dateFormatterTest setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
[dateFormatterTest setLocale:[NSLocale currentLocale]];
NSDate *d = [dateFormatterTest dateFromString:dateStr];

Set NSLocale in your code, and you get perfect result.

the default locale is the current locale, and it's useless. – chancyWu Dec 23 '13 at 06:37
The problem is not that he didn't set a locale. The problem is he didn't use a date formatter. – Léo Natan Dec 23 '13 at 06:37

You can try this:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat: @"yyyy-MM-dd HH:mm:ss"];
[dateFormatter setTimeZone:[NSTimeZone systemTimeZone]];

NSDate *lastUpdatedate = [dateFormatter dateFromString:dateStr];

NSTimeInterval sourceGMTOffset = [[NSTimeZone systemTimeZone] secondsFromGMTForDate:lastUpdatedate];

lastUpdatedate = [lastUpdatedate dateByAddingTimeInterval:sourceGMTOffset];

NSLog(@"lastUpdatedate : %@",lastUpdatedate);

This modifies the parsed `NSDate` object, and is incorrect. – Léo Natan Dec 23 '13 at 06:40
@LeoNatan I didn't get you. Please eloberate more. – Bhumeshwer katre Dec 23 '13 at 06:41
