Unfortunately, it's worse than that.  I've only realised as I've been
phrasing this query, but look closely at the data I've quoted above.
That's really how it is!

I don't think any algorithm will cope with it.

Happily, I need only to *extract* the data - I don't need to keep using
it, so I can convert things to proper dates as I extract.

I was just wondering whether there was some kind of sound design pattern
behind this, or it was just a bit of a brain-fart.
