The same will apply when building that deb package multiple times, the timestamps will change for the ar headers. And I don't really want to lose that data, because currently is the only place were the build time information is recorded. Do you only care that the members themselves are deterministic or the whole deb package? I think I'd be fine with not storing the timestamps in the compressed members themselves, but not about the ar container.
