high-precision mechanical timekeepers (pendulum clocks, etc).

There's an interesting clock at Cambridge university too:

you might consider visiting.  Cambridge is not too far from London,  and a
nice place to visit,  especially on a warm sunny day when punting on the
river Cam would be particularly enjoyable.

I am sure that you will visit Big Ben.

The clocks at NPL were open to the public at the recent open day, but will
not generally be open.  But if you tried a personal phone call,  and said
that you were a tourist with a particular interest in precision
timekeeping,  you might be offered the chance to look around.

There is a really good book about the man who won the British Admiralty prize for constructing and testing an accurate clock for determining longitude at sea.

“Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time,” by Dava Sobel (Author).

My notes on the Corpus Clock: http://fanf.livejournal.com/98545.html

The clock in Trinity College is a smaller version of the Big Ben clock and
has its own web site with interesting technical details:

(I suspect its keeper might be willing to show visiting time nuts around!)

later. Moderate, occasionally slight. Showers, rain later. Good, occasionally
moderate later.

Hi Richard:

Also a movie with the same title.

An even bigger problem was finding the latitude.
