Actually, the socket, not the chip... ;-)

Yes, I do agree that it won't be for the faint hearted... A "dirty"
but safer (for the PCB) solution, since the PLCC socket will be trashed
anyway, is to use a small cutting pliar to (carefully) destroy the
socket, then to unsolder each pin individually once all the plastic
parts have been removed.

This said, an adapter is still the best solution. A quick search on
the web lead me to this:

Not sure how mush it costs, but maybe not much more than the
RTC+battery chip as sold by Farnell... ;-P
