maybe it’s too late to answer, but you need to create a lifecycles.js file in the /content-type/{collection_name}/ folder and add the following code for DateTime field:

module.exports = {
  async beforeCreate(event) {
    const {data} = event.params
    data.your_date_field = new Date();
  }
}

For date field use: new Date().toISOString().substring(0, 10);
