Rust - reproduible Windows exe builds - removing PE timestamps
Raw
README.md

For improved reproduciblity, you can build windows executables without the PE timestamps via mingw-w64 by setting:

RUSTFLAGS='-Clink-arg=-Wl,--no-insert-timestamp'

You may use something like this to conditionally set these flags for Windows builds only:

RUSTFLAGS="$RUSTFLAGS $([[ $platform != *"-windows-"* ]] || echo '-Clink-arg=-Wl,--no-insert-timestamp')" \
  cargo build --target $platform

See: https://wiki.debian.org/ReproducibleBuilds/TimestampsInPEBinaries#building_with_mingw-w64
