Calendar -isDateInToday:date 00:15 not in today?

I am trying to compare if a time is in today. I used the NSCalendar [Calender isDateInToday:date] method. However, a time just passed midnight fail the test. Time 00:14:05 returns NO but 21:43:47 returns YES.

My test code:

NSCalendar *cal = [NSCalendar calendarWithIdentifier: NSCalendarIdentifierGregorian]; 
NSLog(@"date: %@, isInToday: %i, Currernt date: %@", o.deliverDate, [cal isDate:o.deliverDate inSameDayAsDate:[TimeIntervals getCurrerntLocalTime]], [TimeIntervals getCurrerntLocalTime]);

where[TimeIntervals getCurrerntLocalTime] returns current local system time:

+(NSDate *)getCurrerntLocalTime{
NSDate* sourceDate = [NSDate date];

NSTimeZone* sourceTimeZone = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
NSTimeZone* destinationTimeZone = [NSTimeZone systemTimeZone];

NSInteger sourceGMTOffset = [sourceTimeZone secondsFromGMTForDate:sourceDate];
NSInteger destinationGMTOffset = [destinationTimeZone secondsFromGMTForDate:sourceDate];
NSTimeInterval interval = destinationGMTOffset - sourceGMTOffset;

NSDate* destinationDate = [[NSDate alloc] initWithTimeInterval:interval sinceDate:sourceDate];
return destinationDate;
}

And result is:

date: 2015-02-09 00:14:05 +0000, isInToday: 0, Currernt date: 2015-02-09 19:07:43 +0000
date: 2015-02-09 21:43:47 +0000, isInToday: 1, Currernt date: 2015-02-09 19:07:44 +0000

Any suggestions?

You should take your current Calendar:

In swift:

let isToday = NSCalendar.currentCalendar().isDateInToday(date)
