Minimal reproduction of timestamp bug in webpack-cli watch mode

Minimal reproduction of a bug in webpack-cli causing the timestamp that gets output on file change to be off by 1000x

Steps to reproduce:

  • Use this file set
  • Run npm watch
  • Modify the index.js file to trigger a recompile

The modified datetime that is specified in the resulting log will be tens of thousands of years in the future. Valid as of webpack-cli v4.9.2
