If the ``-c'' flag is used, then each argument is taken to be a time_t and is output in ctime format.
If the ``-n'' flag is used, then each argument is taken as a date string to be parsed by parsedate(3) and is output as a time_t; see time(2).
If the ``-s'' flag is used, then each argument is taken as a date string to be parsed by parsedate(3) and is output as a string formatted by ctime(3). This is the default.
