I've broken down my builds into multiple like this:

async function sequentialBuild() {
  await build(buildAllConfig);
  await build(buildCoreConfig);
  await build(buildBlocksConfig);
  for (const config of groupedLayout) {
    await buildGroup(config);
  }
  for (const config of groupedElements) {
    await buildGroup(config);
  }
}

and I wanted to add up all the build time in a variable and log it in the terminal after all builds are done.

Currently tsup is showing me something like build success in 832ms after each build. But is there a way I can store that into a variable?
