- * @summary Convert the given argument to an instance of Date.
- *
- * @description
- * Convert the given argument to an instance of Date.
- *
- * If the argument is an instance of Date, the function returns its clone.
- *
- * If the argument is a number, it is treated as a timestamp.
- *
- * If the argument is none of the above, the function returns Invalid Date.
- *
- * **Note**: *all* Date arguments passed to any *date-fns* function is processed by `toDate`.
- *
- * @param {Date|Number} argument - the value to convert
- * @returns {Date} the parsed date in the local time zone
- * @throws {TypeError} 1 argument required
- *
- * @example
- * // Clone the date:
- * const result = toDate(new Date(2014, 1, 11, 11, 30, 30))
- * //=> Tue Feb 11 2014 11:30:30
- *
- * @example
- * // Convert the timestamp to date:
- * const result = toDate(1392098430000)
- * //=> Tue Feb 11 2014 11:30:30
