Imagine that a virtual filesystem has to make up metadata for an object not actually stored, e.g. a directory for a file system backed by a source code control system that does not have directory artifacts.  Filesystem authors are likely to pick the value 0 for timestamps, even though that is likely to cause trouble (later than 2000 is much safer).
