Timestamp in verbose logs is incorrect by a factor of 1000x

[ryanwilsonperkin]

Describe the bug

When running webpack build --watch with an infrastructure log level of debug, any time a file is changed a log line will be emitted that specifies which file changed and what the time was of the change. This time is incorrect because of a calculation on the initial timestamp, causing the real datetime Changed time is Fri Apr 8 2022 09:56:00 EST-0400 (Eastern Daylight Time) to be reported as Changed time is Mon Mar 26 54238 16:04:29 GMT-0400 (Eastern Daylight Time)

What is the current behavior?

Reports a datetime that is tens of thousands of years in the future 😄

To Reproduce

Here's a minimal reproduction: https://gist.github.com/ryanwilsonperkin/9b14fcc354e6c24df99c9985e1fa5ccd

Steps to reproduce the behavior:

1. Set infrastructure logging level to debug
2. Run a build in watch mode
3. Modify one of the entry files to trigger a recompile
4. Note that the modified datetime that is specified in the resulting log will be incorrect

Expected behavior

Expected the datetime to be accurate
