## @deftypefn {} {@var{str} =} ctime (@var{t})
## Convert a value returned from @code{time} (or any other non-negative
## integer), to the local time and return a string of the same form as
## @code{asctime}.
##
## The function @code{ctime (time)} is equivalent to
## @code{asctime (localtime (time))}.  For example:
##
## @example
## @group
## ctime (time ())
##    @result{} "Mon Feb 17 01:15:06 1997@backslashchar{}n"
## @end group
## @end example
## @seealso{asctime, time, localtime}
## @end deftypefn

function str = ctime (t)

  if (nargin != 1)
    print_usage ();
  endif

  str = asctime (localtime (t));

endfunction


%!test
%! t = time ();
%! assert (strcmp (asctime (localtime (t)), ctime (t)));

%!assert (ctime (time ())(end), "\n")

%!error <Invalid call> ctime ()
