NSDateFormatter SetDateStyle / setTimeStyle not working

[Edwin Ancaer]

Hello,

I hardly dare to suggest it, but I have got the impression that the methods setDateStyle & setTimeStyle have no influence on the result of the method stringFromDate, as you can see in the examples below.

Is it me, again not having understood the workings of these classes completely, or is there really a problem?

I'm on FreeBSD 11.0, with gnustep installed from the ports.

Examples:

  NSDate* d = [NSDate date];  
  NSLog(@"the date as date object             %@", d);
    
2017-08-25 06:20:32.673 TM1[1295:100101] the date as date object             2017-08-25 06:20:32 +0200        


  NSDateFormatter* format = [[NSDateFormatter alloc] init];
  NSLog(@"Dateformatter defaults");
  NSLog(@"  DateFormatter timezone: %@", [format timeZone]);
  NSLog(@"  DateFormatter locale: %@", [format locale]);
  NSLog(@"  DateFormatter datestyle: %u", [format dateStyle]);
  NSLog(@"  DateFormatter timestyle: %u", [format timeStyle]);
  NSLog(@"  Date formatted with defaults      %@", [format stringFromDate: d]);

Could someone tell me what the problem is here?

Thanks,
