`fs.attributes` gives bad modified timestamp for directories on windows

[JakeTrevor]

Describe the bug
The modifed timestamp on windows seems to be bugged.
It works fine for files, but for directories, it keeps ticking up even if no change has been made.

To Reproduce
Steps to reproduce the behavior:

1. Create the following file:

-- watch.lua
local function watch(fname)
    while (true) do
        sleep(1)
        print(fs.attributes(fname).modified)
    end
end

watch('hello')

3. create the watched folder e.g. mkdir hello
4. run bg watch
5. observe that timestamp continually ticks up, even if folder has not been changed.

Expected behavior
timestamp should only tick up when the folder is actually changed - e.g. a file within it is created, etc.
