/**
 * @name parseJSON
 * @category Common Helpers
 * @summary Parse a JSON date string
 *
 * @description
 * Converts a complete ISO date string in UTC time, the typical format for transmitting
 * a date in JSON, to a JavaScript `Date` instance.
 *
 * This is a minimal implementation for converting dates retrieved from a JSON API to
 * a `Date` instance which can be used with other functions in the `date-fns` library.
 * The following formats are supported:
 *
 * - `2000-03-15T05:20:10.123Z`: The output of `.toISOString()` and `JSON.stringify(new Date())`
 * - `2000-03-15T05:20:10Z`: Without milliseconds
 * - `2000-03-15T05:20:10+00:00`: With a zero offset, the default JSON encoded format in some other languages
 * - `2000-03-15T05:20:10+05:45`: With a positive or negative offset, the default JSON encoded format in some other languages
 * - `2000-03-15T05:20:10+0000`: With a zero offset without a colon
 * - `2000-03-15T05:20:10`: Without a trailing 'Z' symbol
 * - `2000-03-15T05:20:10.1234567`: Up to 7 digits in milliseconds field. Only first 3 are taken into account since JS does not allow fractional milliseconds
 * - `2000-03-15 05:20:10`: With a space instead of a 'T' separator for APIs returning a SQL date without reformatting
 *
 * For convenience and ease of use these other input types are also supported
 * via [toDate]{@link https://date-fns.org/docs/toDate}:
 *
 * - A `Date` instance will be cloned
 * - A `number` will be treated as a timestamp
 *
 * Any other input type or invalid date strings will return an `Invalid Date`.
 *
 * @param {String|Number|Date} argument A fully formed ISO8601 date string to convert
 * @returns {Date} the parsed date in the local time zone
 * @throws {TypeError} 1 argument required
