Hi,

Why this code doesn’t works fine ?! tmpDate != dateNew

{ NSDate *tmpDate = [NSDate date];

NSNumber *tmpNum = [NSNumber numberWithFloat:[tmpDate timeIntervalSince1970]];    
NSDate *dateNew = [NSDate dateWithTimeIntervalSince1970:[tmpNum floatValue]];

NSLog(@"%@", [tmpDate descriptionWithLocale:nil]);
NSLog(@"%@", [dateNew descriptionWithLocale:nil]);   }

You must use double instead of float

{ NSDate *tmpDate = [NSDate date];

NSNumber *tmpDouble = [NSNumber numberWithDouble:[tmpDate timeIntervalSince1970]];
NSDate *dateNew = [NSDate dateWithTimeIntervalSince1970:[tmpDouble doubleValue]];

NSLog(@"%@", [tmpDate descriptionWithLocale:nil]);
NSLog(@"%@", [dateNew descriptionWithLocale:nil]);   }
