I disagree that a timestamp is a “build number”. Additionally, injecting dates/times into builds is bad juju from a reproducibility perspective.
Preferably you'd have a build server where you can use the build number. I use this to build my macOS application in GitHub Actions.
[[ $GITHUB_REF_TYPE = "tag" ]] && MARKETING_VERSION=$GITHUB_REF_NAME || MARKETING_VERSION=$(git rev-parse --short HEAD)
echo "Building $MARKETING_VERSION ($GITHUB_RUN_NUMBER)"
agvtool new-version -all $GITHUB_RUN_NUMBER
agvtool new-marketing-version $MARKETING_VERSION
Agreed, CI-managed build numbers are a good way of handling this. I've done the same thing at my past handful of jobs.
