Version: 4.3.1-4

Hi,

While working on the "reproducible builds" effort [1], we have noticed
that libitpp could not be built reproducibly.

The attached patch replaces the timestamp in the docs with the latest
debian/changelog entry timestamp. Once applied, libitpp can be built
reproducibly in our current experimental framework.
