The fix would be quite easy:

  year := (inputStream next: 2) asInteger

should be

  year := 2000 + (inputStream next: 2) asInteger

A more important problem is that there are no users of #readFrom:pattern: in the system, not even unit tests. If we want to keep the methods, someone should start by writing a couple of unit tests.
