DirectoryOptions - mtime does not get used

[viyaha]

Setup:

Node: 14.17.1
mock-fs: 5.0.0

Specification of the mtime in a directory call gets ignored, all other timestamps are working as expected.

import { statSync } from "fs";
import mock from "mock-fs";
import { directory, file } from "mock-fs/lib/filesystem";


mock({
    "C:\\test": directory({mtime: new Date(1), ctime: new Date(1), atime: new Date(1), birthtime: new Date(1)}),
    "C:\\test\\test.txt": file({mtime: new Date(1), ctime: new Date(1), atime: new Date(1), birthtime: new Date(1)}),
});

console.log(statSync("C:\\test"));
console.log(statSync("C:\\test\\test.txt"));

Result:
