Sorry, I forgot to mention ast-open's -p/--parse (already there
in 2004) which predates busybox' -D (2006):

  -p, --parse=format
                  Add format to the list of strptime(3) parse conversion
                  formats. format follows the same conventions as the --format
                  option, with the addition of these format fields:
                    |     If the format failed before this point then restart
                          the parse with the remaining format.
                    &     Call the tmdate(3) heuristic parser. This is is the
                          default when --parse is omitted.
