Hi,

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

The attached patch removes timestamps from the build system. Once
applied, twitter-bootstrap can be built reproducibly in our current
experimental framework.

An alternative solution might be to simply remove the bootstrap.zip from
the final .deb - it does not (or should not!) be used from inside the
-doc package anyway.
