The 'expiry date' in LaTeX2e was there for good reasons, and reflected a
desire to avoid buggy and out-of-date software remaining 'in use' for
too long. However, the situation has changed more recently, as updates
to LaTeX2e have become very rare and the 'expiry date' was no longer
appropriate. The latest LaTeX2e release no longer includes an expiry
date. Clearly, there is not much that can be done directly about the
older version: if you have it, your options are to update at least that
file (latex.ltx), or has been suggested earlier to temporarily 'mess
about' with your system date.
