   * @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 argument is null, it is treated as an invalid date.
   *
   * If all above fails, the function passes the given argument to Date constructor.
   *
   * **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} [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
   * @returns {Date} 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:
   * var 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:
   * var result = toDate('+02014101', {additionalDigits: 1})
   * //=> Fri Apr 11 2014 00:00:00

   * Values will be assigned to the date in the ascending order of its unit's priority.
   * Units of an equal priority overwrite each other in the order of appearance.
   *
   * If no values of higher priority are parsed (e.g. when parsing string 'January 1st' without a year),
   * the values will be taken from 3rd argument `baseDate` which works as a context of parsing.
   *
   * `baseDate` must be passed for correct work of the function.
   * If you're not sure which `baseDate` to supply, create a new instance of Date:
   * `parse('02/11/2014', 'MM/DD/YYYY', new Date())`
   * In this case parsing will be done in the context of the current date.
   * If `baseDate` is `Invalid Date` or a value not convertible to valid `Date`,
   * then `Invalid Date` will be returned.
   *
   * Also, `parse` unfolds long formats like those in [format]{@link https://date-fns.org/docs/format}:

   *
   * The result may vary by locale.
   *
   * If `formatString` matches with `dateString` but does not provides tokens, `baseDate` will be returned.
