+## @deftypefn {Function File} {} 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"
+## @end group
+## @end example
+## @seealso{asctime, time, localtime}
