 * Checks whether the combination of a given date & time input is in the past.
 * NOTE: This additional validation will only work for containers. They get the

 *
 * @param {object} data A page's formData.
 * @param {object} config An additionalValidation config obj.
 * @param {object} container A config obj for a container.
 * @returns True if the date & time are in the past, or there are errors with
 * the individual components. False if the date & time is in the future, or
 * the date/time component can't be found.
