How to use the @lhci/utils/src/build-context.js.getCommitTime function in @lhci/utils

const ancestorHash =
    branch === 'master' ? getAncestorHashForMaster() : getAncestorHashForBranch();

  const build = await api.createBuild({

    author: getAuthor(hash),
    avatarUrl: getAvatarUrl(hash),
    externalBuildUrl: getExternalBuildUrl(),
    runAt: new Date().toISOString(),
    committedAt: getCommitTime(hash),
    ancestorCommittedAt: ancestorHash ? getCommitTime(ancestorHash) : undefined,
  });

  print(`Saving CI project ${project.name} (${project.id})\n`);
  print(`Saving CI build (${build.id})\n`);

  const lhrs = loadSavedLHRs();
  const urlReplacementPatterns = options.urlReplacementPatterns.filter(Boolean);
  const targetUrlMap = new Map();

  const buildViewUrl = new URL(
    `/app/projects/${project.slug}/compare/${build.id}`,
    options.serverBaseUrl
  );

  for (const lhr of lhrs) {
    const parsedLHR = JSON.parse(lhr);
