      :-)

      Have you benchmarked your new implementation versus the current one?
      It's important that the parsing is performant, otherwise it'd slow down
      many things that parse a large number of date strings.

   No benchmarking; I will do that presently.

Benchmarking code and results attached.  I extracted a handful of
non-error cases from the tests as being more representative than any of
the error cases; the resulting numbers make it seem like any difference
between the two implementations is in the noise.

   But this is my first foray into elisp benchmarking, so I may have
overlooked something.  Fortunately, email dates are not that diverse, so
I am hoping this sampling may be broad enough.
