BigIntSupport
BigIntSupport 插件擴充了 dayjs() 和 dayjs.unix() API，使其支援 BigInt 類型參數。
javascript
var bigIntSupport = require('dayjs/plugin/bigIntSupport');
// import bigIntSupport from 'dayjs/plugin/bigIntSupport' // ES 2015
dayjs.extend(bigIntSupport);
dayjs(BigInt(1666310421101));
dayjs.unix(BigInt(1666311003));
