| # on its own, outside of this script. Search for "Bazel workspace status" for |

| # git for stability across multiple invocations of the `bazel` command. Use UTC |
| # rather than committer or local timezones for consistency across build |
| # environments. Use commit date instead of author date, the default date shown |
| # by `git log` and GitHub, because amending, rebasing, merging, etc. can cause |
| # the author date of descendent commits to be earlier than those of their |
| # ancestors. |
| # |
| # Comparable commit dates can be produced via: |
| # `TZ=UTC0 git log --pretty=fuller --date=local`. |
