Appalling! All the clockmaker had to do was use a sundial to set his
clock at noon.

Wasn't the whole point of a ship's chronometer it wasn't set to local time
but to say GMT.
Otherwise its not a lot of use in finding your longitude.

It's a parable. Of course with the correct angle of dangle and a bit of
maths,...
