 * @name toDate
 * @category Common Helpers
 * @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 an argument is a string, the function tries to parse it.
 * Function accepts complete ISO 8601 formats as well as partial implementations.
 * ISO 8601: http://en.wikipedia.org/wiki/ISO_8601
 * If the function cannot parse the string or the values are invalid, it returns Invalid Date.
 *
 * 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`.
 * All *date-fns* functions will throw `RangeError` if `options.additionalDigits` is not 0, 1, 2 or undefined.
 *
 * @param argument the value to convert
 * @param options the object with options. See [Options]{@link https://date-fns.org/docs/Options}
 * @param {0|1|2} [options.additionalDigits=2] - the additional number of digits in the extended year format
 * @param {string} [options.timeZone=''] - used to specify the IANA time zone offset of a date String.
 *
 * @returns the parsed date in the local time zone
 * @throws {TypeError} 1 argument required
 * @throws {RangeError} `options.additionalDigits` must be 0, 1 or 2
 *
 * @example
 * // Convert string '2014-02-11T11:30:30' to date:
 * const result = toDate('2014-02-11T11:30:30')
 * //=> Tue Feb 11 2014 11:30:30
 *
 * @example
 * // Convert string '+02014101' to date,
 * // if the additional number of digits in the extended year format is 1:
 * const result = toDate('+02014101', {additionalDigits: 1})
 * //=> Fri Apr 11 2014 00:00:00
