As a follow-up to this, I found that overriding -dateFormat doesn't
work. It still picks up the format from the tokens in IB. I found I
needed to override -initWithDateFormat instead:

- (id)initWithDateFormat:(NSString *)format
allowNaturalLanguage:(BOOL)flag
{
   NSString *formatJF;
   
   formatJF = [[NSUserDefaults standardUserDefaults] stringForKey:
NSShortDateFormatString];
   self = [super initWithDateFormat:formatJF allowNaturalLanguage:flag];
   return self;
}

Not really sure why this should be, but the docs do actually say "You
must specify a format string whenever you create a date formatter".
