In Haskell's Turtle library, how to copy a file, but preserve the file date

Question

I copy a file with the Turtle library. I do so like this:

...
    do
        TU.cp oldname newname
...

However this sets the date of the copied file to the current time - how can I keep the original date as a shell would do with cp -p?

I don't think this is possible with Turtle. Maybe you could try copyFileWithMetadata instead. — chi

@chi Works! Would you mind writing it up as an answer? I know I asked for a way with Turtle but this is probably the next best thing. — halloleo

It looks like Turtle does not allow that.

You can however use copyFileWithMetadata in System.Directory (part of base) instead.
