Batch copy time creation and modification date from files using OSX

Since this is not working for you I'm going to suggest you do as fd0 suggested and use SetFile. This will be used in conjunction with GetFileInfo, both of which are a part of Command Line Tools for Xcode.

You do not need to install the Xcode.app which is ~3.80 GB, just ~160 MB for Command Line Tools for Xcode.

In Terminal: xcode-select --install

See How to Install Command Line Tools in OS X Mavericks & Yosemite (Without Xcode), which is also for OS X El Capitan.

Here is a bash script to use with SetFile and GetFileInfo:

#!/bin/bash

for f in *; do

    if [[ -f $f ]] && [[ ${f##*.} == MXF ]] && [[ -f ${f%.*}.mov ]]; then

        cDate="$(GetFileInfo -d "$f")"
        mDate="$(GetFileInfo -m "$f")"

        SetFile -d "$cDate" -m "$mDate" "${f%.*}.mov"

    fi

done
