Go builds are, in general, reproducible by default. Build stamps do not change this.

  "reproducible by default" if the system is setup a certain way. Build time injected into builds would absolutely break any reproducibility.

    It would, which is why the Go compiler and linker do not put the build time in binaries.

      But you literally said "build stamps do not change this", and it absolutely does. Of course as I mentioned it does not look like go is adding a build time to the binary.

    > "reproducible by default" if the system is setup a certain way What do you mean? Under what circumstances is a Go build not reproducible? From what I’ve observed, if you build your binary with a set of input, the same binary is produced. Is it sometimes not true?

      By default you need the same GOPATH and GOROOT. Compiler version must be identical (not a huge stretch). cgo reproducibility is not a guarantee.
