kk-date/test/other.test.js

kk-date is a fastest JavaScript library that parses, validations, manipulates, and displays dates and times. If you use Moment.js or Day.js already you can easily use kk-date.

const { describe, test, expect } = require('@jest/globals');
const kk_date = require('../index');
const test_date = '2024-08-19';
const test_time = '23:50:59';

const timezone = 'UTC';

kk_date.config({ timezone: timezone });
