11.1. Formatowanie dat podczas wyświetlania
Problem
Chcemy sformatować ciągi daty i czasu, które mają zostać wyświetlone.
Rozwiązanie
Należy wykorzystać polecenie date z uwzględnieniem specyfikacji formatu dla funkcji strftime. Zestawienie obsługiwanych symboli formatu zostało zamieszczone w Dodatek A, w punkcie „Formatowanie daty i czasu z wykorzystaniem funkcji strftime”, oraz na stronach podręcznika systemowego funkcji strftime.
