## @deftypefn {} {} asctime (@var{tm_struct})
## Convert a time structure to a string using the following
## format: @qcode{"ddd mmm mm HH:MM:SS yyyy@xbackslashchar{}n"}.
##
## For example:
##
## @example
## @group
## asctime (localtime (time ()))
##      @result{} "Mon Feb 17 01:15:06 1997@xbackslashchar{}n"
## @end group
## @end example
##
## This is equivalent to @code{ctime (time ())}.
## @seealso{ctime, localtime, time}
## @end deftypefn
