While organizing most of my information in Markdown files meanwhile, I like to have some metadata in each file to see e.g. when files have been created and/or updated.
The Auto Time Stamp extension is a small extension that doe exactly this for you. By adding Created: and/or Last modified: the extension will update these fields automatically when the file is saved.

This extension is going into my must-have toolbox for VS Code.
