load("@aspect_bazel_lib//lib:expand_template.bzl", "expand_template")


expand_template(
        name = "labels",
        out = "labels.txt",
        stamp = 1,
        stamp_substitutions = {
            "{{_BUILD_TIME}}": "{{FORMATTED_DATE}}",
        },
        template = [
            "BUILD_TIME={{_BUILD_TIME}}",
        ],
    )
