Hello,
I'm looking for a CommonLisp library function that might help me to
parse a date/time string. I couldn't really find anything suitable
via a web search but it seems like a common enough task that it must
have been solved at least once!
I was interested in something similar (but not necessarily
identical!) to .NET's DateTime.ParseExact (which accepts culture info
and a string of permissible date format strings).
Anyone know of any such function? Or am I going to have to get my
hands dirty?

A quick look on cliki suggests to me that you might have to get your
hands dirty but there was something that you might be able to dust off
and get going again. The wayback machine has a reference to
http://web.archive.org/web/20040808070352/http://www.lisp-p.org/pdl/
...which claims to be a lisp date parsing lib.

There are many.
See CLOCC or this:
http://www.cliki.net/net-telent-date
On a Lisp Machine just call TIME:PARSE .
I had no idea about CLOCC! Looks like there's a lot of interesting
stuff in here, thanks.
Though, I think I'll probably use Sean's cl-l10n library because it
supports cultures/locales.
Many thanks
Steve

CL-L10N also has a port of this which adds some support for non-
english date formats.

Perfect. Thanks Sean.

Well, the open-source CMUCL has such a package. It is what we have used
(with notice to the developers of CMUCL) as part of our Loom code. It
works quite nicely, and is also reasonably extensible to additional date
formats.
EXTENSIONS:PARSE-TIME is the name of the function. It is defined,
logically enough, in the parse-time.lisp file in the CMUCL sources.
