 modified time of the package folder is unaffected.
For example, if you add a file to <code>node_modules/foo/lib/bar.js</code>, then the
modified time on <code>node_modules/foo</code> will not reflect this change.  If you
are manually editing files in <code>node_modules</code>, it is generally best to
delete the file at <code>node_modules/.package-lock.json</code>.</p>
<p>As the hidden lockfile is ignored by older npm versions, it does not
contain the backwards compatibility affordances present in "normal"
