+ * @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)
