Importing sample content causes NFS Container to fail on local environment

When trying to import the sample content by uncommenting WORDPRESS_TEST_DATA=true in the _env file in combination with docker-compose -f local-compose up -d on both boot2docker and Docker for Mac, the NFS container fails with the following error:

fs.js:882
  throw new Error('Cannot parse time: ' + time);
        ^
