/**

* @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
